feat: add non-interactive flag to create command

This will automatically select the template if there is only one, skip the preset if there is no default, and use parameter defaults. If there are multiple templates or required parameters that have no defaults, the command will error.

-# Modern Go (1.18–1.26)
-
-Reference for writing idiomatic Go. Covers what changed, what it
-replaced, and what to reach for. Respect the project's `go.mod` `go`
-line: don't emit features from a version newer than what the module
-declares. Check `go.mod` before writing code.
-
-## How modern Go thinks differently
-
-**Generics** (1.18): Design reusable code with type parameters instead
-of `interface{}` casts, code generation, or the `sort.Interface`
-pattern. Use `any` for unconstrained types, `comparable` for map keys
-and equality, `cmp.Ordered` for sortable types. Type inference usually
-makes explicit type arguments unnecessary (improved in 1.21).
-
-**Per-iteration loop variables** (1.22): Each loop iteration gets its
-own variable copy. Closures inside loops capture the correct value. The
-`v := v` shadow trick is dead. Remove it when you see it.
-
-**Iterators** (1.23): `iter.Seq[V]` and `iter.Seq2[K,V]` are the
-standard iterator types. Containers expose `.All()` methods returning
-these. Combined with `slices.Collect`, `slices.Sorted`, `maps.Keys`,
-etc., they replace ad-hoc "loop and append" code with composable,
-lazy pipelines. When a sequence is consumed only once, prefer an
-iterator over materializing a slice.
-
-**Error trees** (1.20–1.26): Errors compose as trees, not chains.
-`errors.Join` aggregates multiple errors. `fmt.Errorf` accepts multiple
-`%w` verbs. `errors.Is`/`As` traverse the full tree. Custom error
-types that wrap multiple causes must implement `Unwrap() []error` (the
-slice form), not `Unwrap() error`, or tree traversal won't find the
-children. `errors.AsType[T]` (1.26) is the type-safe way to match
-error types. Propagate cancellation reasons with
-`context.WithCancelCause`.
-
-**Structured logging** (1.21): `log/slog` is the standard structured
-logger. This project uses `cdr.dev/slog/v3` instead, which has a
-different API. Do not use `log/slog` directly.
-
-## Replace these patterns
-
-The left column reflects common patterns from pre-1.22 Go. Write the
-right column instead. The "Since" column tells you the minimum `go`
-directive version required in `go.mod`.
-
-| Old pattern | Modern replacement | Since |
-|---|---|---|
-| `interface{}` | `any` | 1.18 |
-| `v := v` inside loops | remove it | 1.22 |
-| `for i := 0; i < n; i++` | `for i := range n` | 1.22 |
-| `for i := 0; i < b.N; i++` (benchmarks) | `for b.Loop()` (correct timing, future-proof) | 1.24 |
-| `sort.Slice(s, func(i,j int) bool{…})` | `slices.SortFunc(s, cmpFn)` | 1.21 |
-| `wg.Add(1); go func(){ defer wg.Done(); … }()` | `wg.Go(func(){…})` | 1.25 |
-| `func ptr[T any](v T) *T { return &v }` | `new(expr)` e.g. `new(time.Now())` | 1.26 |
-| `var target *E; errors.As(err, &target)` | `t, ok := errors.AsType[*E](err)` | 1.26 |
-| Custom multi-error type | `errors.Join(err1, err2, …)` | 1.20 |
-| Single `%w` for multiple causes | `fmt.Errorf("…: %w, %w", e1, e2)` | 1.20 |
-| `rand.Seed(time.Now().UnixNano())` | delete it (auto-seeded); prefer `math/rand/v2` | 1.20/1.22 |
-| `sync.Once` + captured variable | `sync.OnceValue(func() T {…})` / `OnceValues` | 1.21 |
-| Custom `min`/`max` helpers | `min(a, b)` / `max(a, b)` builtins (any ordered type) | 1.21 |
-| `for k := range m { delete(m, k) }` | `clear(m)` (also zeroes slices) | 1.21 |
-| Index+slice or `SplitN(s, sep, 2)` | `strings.Cut(s, sep)` / `bytes.Cut` | 1.18 |
-| `TrimPrefix` + check if anything was trimmed | `strings.CutPrefix` / `CutSuffix` (returns ok bool) | 1.20 |
-| `strings.Split` + loop when no slice is needed | `strings.SplitSeq` / `Lines` / `FieldsSeq` (iterator, no alloc) | 1.24 |
-| `"2006-01-02"` / `"2006-01-02 15:04:05"` / `"15:04:05"` | `time.DateOnly` / `time.DateTime` / `time.TimeOnly` | 1.20 |
-| Manual `Before`/`After`/`Equal` chains for comparison | `time.Time.Compare` (returns -1/0/+1; works with `slices.SortFunc`) | 1.20 |
-| Loop collecting map keys into slice | `slices.Sorted(maps.Keys(m))` | 1.23 |
-| `fmt.Sprintf` + append to `[]byte` | `fmt.Appendf(buf, …)` (also `Append`, `Appendln`) | 1.18 |
-| `reflect.TypeOf((*T)(nil)).Elem()` | `reflect.TypeFor[T]()` | 1.22 |
-| `*(*[4]byte)(slice)` unsafe cast | `[4]byte(slice)` direct conversion | 1.20 |
-| `atomic.LoadInt64` / `StoreInt64` | `atomic.Int64` (also `Bool`, `Uint64`, `Pointer[T]`) | 1.19 |
-| `crypto/rand.Read(buf)` + hex/base64 encode | `crypto/rand.Text()` (one call) | 1.24 |
-| Checking `crypto/rand.Read` error | don't: return is always nil | 1.24 |
-| `time.Sleep` in tests | `testing/synctest` (deterministic fake clock) | 1.24/1.25 |
-| `json:",omitempty"` on zero-value structs like `time.Time{}` | `json:",omitzero"` (uses `IsZero()` method) | 1.24 |
-| `strings.Title` | `golang.org/x/text/cases` | 1.18 |
-| `net.IP` in new code | `net/netip.Addr` (immutable, comparable, lighter) | 1.18 |
-| `tools.go` with blank imports | `tool` directive in `go.mod` | 1.24 |
-| `runtime.SetFinalizer` | `runtime.AddCleanup` (multiple per object, no pointer cycles) | 1.24 |
-| `httputil.ReverseProxy.Director` | `.Rewrite` hook + `ProxyRequest` (Director deprecated in 1.26) | 1.20 |
-| `sql.NullString`, `sql.NullInt64`, etc. | `sql.Null[T]` | 1.22 |
-| Manual `ctx, cancel := context.WithCancel(…)` + `t.Cleanup(cancel)` | `t.Context()` (auto-canceled when test ends) | 1.24 |

-## New capabilities
-
-These enable things that weren't practical before. Reach for them in the
-described situations.
-
-| What | Since | When to use it |
-|---|---|---|
-| `cmp.Or(a, b, c)` | 1.22 | Defaults/fallback chains: returns first non-zero value. Replaces verbose `if a != "" { return a }` cascades. |
-| `context.WithoutCancel(ctx)` | 1.21 | Background work that must outlive the request (e.g. async cleanup after HTTP response). Derived context keeps parent's values but ignores cancellation. |
-| `context.AfterFunc(ctx, fn)` | 1.21 | Register cleanup that fires on context cancellation without spawning a goroutine that blocks on `<-ctx.Done()`. |
-| `context.WithCancelCause` / `Cause` | 1.20 | When callers need to know WHY a context was canceled, not just that it was. Retrieve cause with `context.Cause(ctx)`. |
-| `context.WithDeadlineCause` / `WithTimeoutCause` | 1.21 | Attach a domain-specific error to deadline/timeout expiry (e.g. distinguish "DB query timed out" from "HTTP request timed out"). |
-| `errors.ErrUnsupported` | 1.21 | Standard sentinel for "not supported." Use instead of per-package custom sentinels. Check with `errors.Is`. |
-| `http.ResponseController` | 1.20 | Per-request flush, hijack, and deadline control without type-asserting `ResponseWriter` to `http.Flusher` or `http.Hijacker`. |
-| Enhanced `ServeMux` routing | 1.22 | `"GET /items/{id}"` patterns in `http.ServeMux`. Access with `r.PathValue("id")`. Wildcards: `{name}`, catch-all: `{path...}`, exact: `{$}`. Eliminates many third-party router dependencies. |
-| `os.Root` / `OpenRoot` | 1.24 | Confined directory access that prevents symlink escape. 1.25 adds `MkdirAll`, `ReadFile`, `WriteFile` for real use. |
-| `os.CopyFS` | 1.23 | Copy an entire `fs.FS` to local filesystem in one call. |
-| `os/signal.NotifyContext` with cause | 1.26 | Cancellation cause identifies which signal (SIGTERM vs SIGINT) triggered shutdown. |
-| `io/fs.SkipAll` / `filepath.SkipAll` | 1.20 | Return from `WalkDir` callback to stop walking entirely. Cleaner than a sentinel error. |
-| `GOMEMLIMIT` env / `debug.SetMemoryLimit` | 1.19 | Soft memory limit for GC. Use alongside or instead of `GOGC` in memory-constrained containers. |
-| `net/url.JoinPath` | 1.19 | Join URL path segments correctly. Replaces error-prone string concatenation. |
-| `go test -skip` | 1.20 | Skip tests matching a pattern. Useful when running a subset of a large test suite. |
-
-## Key packages
-
-### `slices` (1.21, iterators added 1.23)
-
-Replaces `sort.Slice`, manual search loops, and manual contains checks.
-
-Search: `Contains`, `ContainsFunc`, `Index`, `IndexFunc`,
-`BinarySearch`, `BinarySearchFunc`.
-
-Sort: `Sort`, `SortFunc`, `SortStableFunc`, `IsSorted`, `IsSortedFunc`,
-`Min`, `MinFunc`, `Max`, `MaxFunc`.
-
-Transform: `Clone`, `Compact`, `CompactFunc`, `Grow`, `Clip`,
-`Concat` (1.22), `Repeat` (1.23), `Reverse`, `Insert`, `Delete`,
-`Replace`.
-
-Compare: `Equal`, `EqualFunc`, `Compare`.
-
-Iterators (1.23): `All`, `Values`, `Backward`, `Collect`, `AppendSeq`,
-`Sorted`, `SortedFunc`, `SortedStableFunc`, `Chunk`.
-
-### `maps` (1.21, iterators added 1.23)
-
-Core: `Clone`, `Copy`, `Equal`, `EqualFunc`, `DeleteFunc`.
-
-Iterators (1.23): `All`, `Keys`, `Values`, `Insert`, `Collect`.
-
-### `cmp` (1.21, `Or` added 1.22)
-
-`Ordered` constraint for any ordered type. `Compare(a, b)` returns
-1/0/+1. `Less(a, b)` returns bool. `Or(vals...)` returns first
-non-zero value.
-
-### `iter` (1.23)
-
-`Seq[V]` is `func(yield func(V) bool)`. `Seq2[K,V]` is
-`func(yield func(K, V) bool)`. Return these from your container's
-`.All()` methods. Consume with `for v := range seq` or pass to
-`slices.Collect`, `slices.Sorted`, `maps.Collect`, etc.
-
-### `math/rand/v2` (1.22)
-
-Replaces `math/rand`. `IntN` not `Intn`. Generic `N[T]()` for any
-integer type. Default source is `ChaCha8` (crypto-quality). No global
-`Seed`. Use `rand.New(source)` for reproducible sequences.
-
-### `log/slog` (1.21)
-
-`slog.Info`, `slog.Warn`, `slog.Error`, `slog.Debug` with key-value
-pairs. `slog.With(attrs...)` for logger with preset fields.
-`slog.GroupAttrs` (1.25) for clean group creation. Implement
-`slog.Handler` for custom backends.
-
-**Note:** This project uses `cdr.dev/slog/v3`, not `log/slog`. The
-API is different. Read existing code for usage patterns.
-
-## Pitfalls
-
-Things that are easy to get wrong, even when you know the modern API
-exists. Check your output against these.
-
-**Version misuse.** The replacement table has a "Since" column. If the
-project's `go.mod` says `go 1.22`, you cannot use `wg.Go` (1.25),
-`errors.AsType` (1.26), `new(expr)` (1.26), `b.Loop()` (1.24), or
-`testing/synctest` (1.24). Fall back to the older pattern. Always
-check before reaching for a replacement.
-
-**`slices.Sort` vs `slices.SortFunc`.** `slices.Sort` requires
-`cmp.Ordered` types (int, string, float64, etc.). For structs, custom
-types, or multi-field sorting, use `slices.SortFunc` with a comparator
-function. Using `slices.Sort` on a non-ordered type is a compile error.
-
-**`for range n` still binds the index.** `for range n` discards the
-index. If you need it, write `for i := range n`. Writing
-`for range n` and then trying to use `i` inside the loop is a compile
-error.
-
-**Don't hand-roll iterators when the stdlib returns one.** Functions
-like `maps.Keys`, `slices.Values`, `strings.SplitSeq`, and
-`strings.Lines` already return `iter.Seq` or `iter.Seq2`. Don't
-reimplement them. Compose with `slices.Collect`, `slices.Sorted`, etc.
-
-**Don't mix `math/rand` and `math/rand/v2`.** They have different
-function names (`Intn` vs `IntN`) and different default sources. Pick
-one per package. Prefer v2 for new code. The v1 global source is
-auto-seeded since 1.20, so delete `rand.Seed` calls either way.
-
-**Iterator protocol.** When implementing `iter.Seq`, you must respect
-the `yield` return value. If `yield` returns `false`, stop iteration
-immediately and return. Ignoring it violates the contract and causes
-panics when consumers break out of `for range` loops early.
-
-**`errors.Join` with nil.** `errors.Join` skips nil arguments. This is
-intentional and useful for aggregating optional errors, but don't
-assume the result is always non-nil. `errors.Join(nil, nil)` returns
-nil.
-
-**`cmp.Or` evaluates all arguments.** Unlike a chain of `if`
-statements, `cmp.Or(a(), b(), c())` calls all three functions. If any
-have side effects or are expensive, use `if`/`else` instead.
-
-**Timer channel semantics changed in 1.23.** Code that checks
-`len(timer.C)` to see if a value is pending no longer works (channel
-capacity is 0). Use a non-blocking `select` receive instead:
-`select { case <-timer.C: default: }`.
-
-**`context.WithoutCancel` still propagates values.** The derived
-context inherits all values from the parent. If any middleware stores
-request-scoped state (deadlines, trace IDs) via `context.WithValue`,
-the background work sees it. This is usually desired but can be
-surprising if the values hold references that should not outlive the
-request.
-
-## Behavioral changes that affect code
-
- **Timers** (1.23): unstopped `Timer`/`Ticker` are GC'd immediately.
-  Channels are unbuffered: no stale values after `Reset`/`Stop`. You no
-  longer need `defer t.Stop()` to prevent leaks.
- **Error tree traversal** (1.20): `errors.Is`/`As` follow
-  `Unwrap() []error`, not just `Unwrap() error`. Multi-error types must
-  expose the slice form for child errors to be found.
- **`math/rand` auto-seeded** (1.20): the global RNG is auto-seeded.
-  `rand.Seed` is a no-op in 1.24+. Don't call it.
- **GODEBUG compat** (1.21): behavioral changes are gated by `go.mod`'s
-  `go` line. Upgrading the version opts into new defaults.
- **Build tags** (1.18): `//go:build` is the only syntax. `// +build`
-  is gone.
- **Tool install** (1.18): `go get` no longer builds. Use
-  `go install pkg@version`.
- **Doc comments** (1.19): support `[links]`, lists, and headings.
- **`go test -skip`** (1.20): skip tests by name pattern from the
-  command line.
- **`go fix ./...` modernizers** (1.26): auto-rewrites code to use
-  newer idioms. Run after Go version upgrades.
-
-## Transparent improvements (no code changes)
-
-Swiss Tables maps, Green Tea GC, PGO, faster `io.ReadAll`,
-stack-allocated slices, reduced cgo overhead, container-aware
-GOMAXPROCS. Free on upgrade.

-
-# Code Review Skill
-
-Review code changes in coder/coder and identify bugs, security issues, and
-quality problems.
-
-## Workflow
-
-1. **Get the code changes** - Use the method provided in the prompt, or if none
-   specified:
-   - For a PR: `gh pr diff <PR_NUMBER> --repo coder/coder`
-   - For local changes: `git diff main` or `git diff --staged`
-
-2. **Read full files and related code** before commenting - verify issues exist
-   and consider how similar code is implemented elsewhere in the codebase
-
-3. **Analyze for issues** - Focus on what could break production
-
-4. **Report findings** - Use the method provided in the prompt, or summarize
-   directly
-
-## Severity Levels
-
- **🔴 CRITICAL**: Security vulnerabilities, auth bypass, data corruption,
-  crashes
- **🟡 IMPORTANT**: Logic bugs, race conditions, resource leaks, unhandled
-  errors
- **🔵 NITPICK**: Minor improvements, style issues, portability concerns
-
-## What to Look For
-
- **Security**: Auth bypass, injection, data exposure, improper access control
- **Correctness**: Logic errors, off-by-one, nil/null handling, error paths
- **Concurrency**: Race conditions, deadlocks, missing synchronization
- **Resources**: Leaks, unclosed handles, missing cleanup
- **Error handling**: Swallowed errors, missing validation, panic paths
-
-## What NOT to Comment On
-
- Style that matches existing Coder patterns (check AGENTS.md first)
- Code that already exists unchanged
- Theoretical issues without concrete impact
- Changes unrelated to the PR's purpose
-
-## Coder-Specific Patterns
-
-### Authorization Context
-
-```go
-// Public endpoints needing system access
-dbauthz.AsSystemRestricted(ctx)
-
-// Authenticated endpoints with user context - just use ctx
-api.Database.GetResource(ctx, id)
-```
-
-### Error Handling
-
-```go
-// OAuth2 endpoints use RFC-compliant errors
-writeOAuth2Error(ctx, rw, http.StatusBadRequest, "invalid_grant", "description")
-
-// Regular endpoints use httpapi
-httpapi.Write(ctx, rw, http.StatusBadRequest, codersdk.Response{...})
-```
-
-### Shell Scripts
-
-`set -u` only catches UNDEFINED variables, not empty strings:
-
-```sh
-unset VAR; echo ${VAR}         # ERROR with set -u
-VAR=""; echo ${VAR}            # OK with set -u (empty is fine)
-VAR="${INPUT:-}"; echo ${VAR}  # OK - always defined
-```
-
-GitHub Actions context variables (`github.*`, `inputs.*`) are always defined.
-
-## Review Quality
-
- Explain **impact** ("causes crash when X" not "could be better")
- Make observations **actionable** with specific fixes
- Read the **full context** before commenting on a line
- Check **AGENTS.md** for project conventions before flagging style
-
-## Comment Standards
-
- **Only comment when confident** - If you're not 80%+ sure it's a real issue,
-  don't comment. Verify claims before posting.
- **No speculation** - Avoid "might", "could", "consider". State facts or skip.
- **Verify technical claims** - Check documentation or code before asserting how
-  something works. Don't guess at API behavior or syntax rules.

+            - Be thorough but accurate - read full files to verify issues exist
+            - Think critically about what could actually go wrong
+            - Make every observation actionable with a suggestion
+            - Refer to AGENTS.md for Coder-specific patterns and conventions

+
+            Examples:
+            - unset VAR; echo \${VAR}         → ERROR with set -u (undefined)
+            - VAR=""; echo \${VAR}            → OK with set -u (defined, just empty)
+            - VAR="\${INPUT:-}"; echo \${VAR} → OK with set -u (always defined, may be empty)
+
+            GitHub Actions context variables (github.*, inputs.*) are ALWAYS defined.
+            They may be empty strings, but they are never undefined.
+
+            Don't comment on set -u unless you see actual undefined variable access.
+          </instructions>
+
+          <github_api_documentation>
+          HOW GITHUB SUGGESTIONS WORK:
+          Your suggestion block REPLACES the commented line(s). Don't include surrounding context!
+
+          Example (fictional):
+          49: # Comment line
+          50: OLDCODE=\$(bad command)
+          51: echo "done"
+
+          ❌ WRONG - includes unchanged lines 49 and 51:
+          {"line": 50, "body": "Issue\\n\\n\`\`\`suggestion\\n# Comment line\\nNEWCODE\\necho \\"done\\"\\n\`\`\`"}
+          Result: Lines 49 and 51 duplicated!
+
+          ✅ CORRECT - only the replacement for line 50:
+          {"line": 50, "body": "Issue\\n\\n\`\`\`suggestion\\nNEWCODE=\$(good command)\\n\`\`\`"}
+          Result: Only line 50 replaced. Perfect!
+
+          COMMENT FORMAT:
+          Single line: {"path": "file.go", "line": 50, "side": "RIGHT", "body": "Issue\\n\\n\`\`\`suggestion\\n[code]\\n\`\`\`"}
+          Multi-line: {"path": "file.go", "start_line": 50, "line": 52, "side": "RIGHT", "body": "Issue\\n\\n\`\`\`suggestion\\n[code]\\n\`\`\`"}
+
+          SUMMARY FORMAT (1-10 lines, conversational):
+          With issues: "## 🔍 Code Review\\n\\nReviewed [5-8 words].\\n\\n**Found X issues** (Y critical, Z nitpicks).\\n\\n---\\n*AI review via [Coder Tasks](https://coder.com/docs/ai-coder/tasks)*"

+
+          <critical_rules>
+          1. Read ENTIRE files before commenting - use read_file or grep to verify
+          2. Check the EXACT line you're commenting on - does the issue actually exist there?
+          3. Suggestion block = ONLY replacement lines (never include unchanged surrounding lines)
+          4. Single line: {"line": 50} | Multi-line: {"start_line": 50, "line": 52}
+          5. Explain IMPACT ("causes crash/leak/bypass" not "could be better")
+          6. Make ALL observations actionable with suggestions (not just summary mentions)
+          7. set -u = undefined vars only. Don't claim it catches empty strings. It doesn't.
+          8. No issues = {"event": "COMMENT", "comments": [], "body": "[summary with Coder Tasks link]"}

-### API Design
-
- Add swagger annotations when introducing new HTTP endpoints. Do this in
-  the same change as the handler so the docs do not get missed before
-  release.
- For user-scoped or resource-scoped routes, prefer path parameters over
-  query parameters when that matches existing route patterns.
- For experimental or unstable API paths, skip public doc generation with
-  `// @x-apidocgen {"skip": true}` after the `@Router` annotation. This
-  keeps them out of the published API reference until they stabilize.
-
-### Database Query Naming
-
- Use `ByX` when `X` is the lookup or filter column.
- Use `PerX` or `GroupedByX` when `X` is the aggregation or grouping
-  dimension.
- Avoid `ByX` names for grouped queries.
-
-### Database-to-SDK Conversions
-
- Extract explicit db-to-SDK conversion helpers instead of inlining large
-  conversion blocks inside handlers.
- Keep nullable-field handling, type coercion, and response shaping in the
-  converter so handlers stay focused on request flow and authorization.

 ## Quick Reference

 ### Full workflows available in imported WORKFLOWS.md

-### Git Hooks (MANDATORY - DO NOT SKIP)
-
-**You MUST install and use the git hooks. NEVER bypass them with
-`--no-verify`. Skipping hooks wastes CI cycles and is unacceptable.**
-
-The first run will be slow as caches warm up. Consecutive runs are
-**significantly faster** (often 10x) thanks to Go build cache,
-generated file timestamps, and warm node_modules. This is NOT a
-reason to skip them. Wait for hooks to complete before proceeding,
-no matter how long they take.
-
-```sh
-git config core.hooksPath scripts/githooks
-```
-
-Two hooks run automatically:
-
- **pre-commit**: `make pre-commit` (gen, fmt, lint, typos, build).
-  Fast checks that catch most CI failures. Allow at least 5 minutes.
- **pre-push**: `make pre-push` (heavier checks including tests).
-  Allowlisted in `scripts/githooks/pre-push`. Runs only for developers
-  who opt in. Allow at least 15 minutes.
-
-`git commit` and `git push` will appear to hang while hooks run.
-This is normal. Do not interrupt, retry, or reduce the timeout.
-
-NEVER run `git config core.hooksPath` to change or disable hooks.
-
-If a hook fails, fix the issue and retry. Do not work around the
-failure by skipping the hook.
-
 ### Git Workflow

 - Follow [Uber Go Style Guide](https://github.com/uber-go/guide/blob/master/style.md)
 - Commit format: `type(scope): message`
- PR titles follow the same `type(scope): message` format.
- When you use a scope, it must be a real filesystem path containing every
-  changed file.
- Use a broader path scope, or omit the scope, for cross-cutting changes.
- Example: `fix(coderd/chatd): ...` for changes only in `coderd/chatd/`.

-### Frontend Patterns
-
- Prefer existing shared UI components and utilities over custom
-  implementations. Reuse common primitives such as loading, table, and error
-  handling components when they fit the use case.
- Use Storybook stories for all component and page testing, including
-  visual presentation, user interactions, keyboard navigation, focus
-  management, and accessibility behavior. Do not create standalone
-  vitest/RTL test files for components or pages. Stories double as living
-  documentation, visual regression coverage, and interaction test suites
-  via `play` functions. Reserve plain vitest files for pure logic only:
-  utility functions, data transformations, hooks tested via
-  `renderHook()` that do not require DOM assertions, and query/cache
-  operations with no rendered output.

-// Metrics tracks observability for the boundary -> agent -> coderd audit log
-// pipeline.
-//
-// Audit logs from boundary workspaces pass through several async buffers
-// before reaching coderd, and any stage can silently drop data. These
-// metrics make that loss visible so operators/devs can:
-//
-//   - Bubble up data loss: a non-zero drop rate means audit logs are being
-//     lost, which may have auditing implications.
-//   - Identify the bottleneck: the reason label pinpoints where drops
-//     occur: boundary's internal buffers, the agent's channel, or the
-//     RPC to coderd.
-//   - Tune buffer sizes: sustained "buffer_full" drops indicate the
-//     agent's channel (or boundary's batch buffer) is too small for the
-//     workload. Combined with batches_forwarded_total you can compute a
-//     drop rate: drops / (drops + forwards).
-//   - Detect batch forwarding issues: "forward_failed" drops increase when
-//     the agent cannot reach coderd.
-//
-// Drops are captured at two stages:
-//   - Agent-side: the agent's channel buffer overflows (reason
-//     "buffer_full") or the RPC forward to coderd fails (reason
-//     "forward_failed").
-//   - Boundary-reported: boundary self-reports drops via BoundaryStatus
-//     messages (reasons "boundary_channel_full", "boundary_batch_full").
-//     These arrive on the next successful flush from boundary.
-//
-// There are circumstances where metrics could be lost e.g., agent restarts,
-// boundary crashes, or the agent shuts down when the DRPC connection is down.
