feat(agent): populate subagent ID for terraform-defined devcontainers

Update the manifest API in coderd to populate the subagent_id field for devcontainers, enabling the agent to receive devcontainer resource definitions with pre-assigned IDs and use them when creating sub-agents. This allows Terraform-defined devcontainers to: - Have stable subagent IDs across workspace rebuilds - Prevent accidental deletion/recreation of managed subagents - Prevent UI-initiated rebuilds of terraform-managed containers
feat(agent): add subagent ID fields to devcontainers in manifest (#21848 )

+description: Reviews code changes for bugs, security issues, and quality problems
+---
+
+# 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.

-          <instructions>
-          YOUR JOB:
-            - Find bugs and security issues that would break production
-            - 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
+          ## Review Format

-          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
+          Create review.json:
+          \`\`\`json
+          {
+            \"event\": \"COMMENT\",
+            \"commit_id\": \"[sha from gh api]\",
+            \"body\": \"## Code Review\\n\\nReviewed [description]. Found X issues.\",
+            \"comments\": [{\"path\": \"file.go\", \"line\": 50, \"side\": \"RIGHT\", \"body\": \"Issue\\n\\n\`\`\`suggestion\\nfix\\n\`\`\`\"}]
+          }
+          \`\`\`

-          COMMENT STYLE:
-            - CRITICAL/IMPORTANT: Standard inline suggestions
-            - NITPICKS: Prefix with "[NITPICK]" in the issue description
-            - All observations must have actionable suggestions (not just summary mentions)
+          - Multi-line comments: add \"start_line\" (range start), \"line\" is range end
+          - Suggestion blocks REPLACE the line(s), don't include surrounding unchanged code

-          DON'T COMMENT ON:
-            ❌ Style that matches existing Coder patterns (check AGENTS.md first)
-            ❌ Code that already exists (read the file first!)
-            ❌ Unnecessary changes unrelated to the PR
+          ## Submit

-          IMPORTANT - UNDERSTAND set -u:
-            set -u only catches UNDEFINED/UNSET variables. It does NOT catch empty strings.
-
-            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]"}

+// Package boundaryusage tracks workspace boundary usage for telemetry reporting.
+// The design intent is to track trends and rough usage patterns.
+//
+// Each replica does in-memory usage tracking. Boundary usage is inferred at the
+// control plane when workspace agents call the ReportBoundaryLogs RPC. Accumulated
+// stats are periodically flushed to a database table keyed by replica ID. Telemetry
+// aggregates are computed across all replicas when generating snapshots.
+//
+// Aggregate Precision:
+//
+// The aggregated stats represent approximate usage over roughly the telemetry
+// snapshot interval, not a precise time window. This imprecision arises because:
+//
+//   - Each replica flushes independently, so their data covers slightly different
+//     time ranges (varying by up to the flush interval)
+//   - Unflushed in-memory data at snapshot time rolls into the next period
+//   - The snapshot captures "data flushed since last reset" rather than "usage
+//     during exactly the last N minutes"
+//
+// We accept this imprecision to keep the architecture simple. Each replica
+// operates independently and flushes to the database on their own schedule.
+// This approach also minimizes database load. The table contains at most one
+// row per replica, so flushes are just upserts, and resets only delete N
+// rows. There's no accumulation of historical data to clean up. The only
+// synchronization is a database lock that ensures exactly one replica reports
+// telemetry per period.
+//
+// Known Shortcomings:
+//
+//   - Unique workspace/user counts may be inflated when the same workspace or
+//     user connects through multiple replicas, as each replica tracks its own
+//     unique set
+//   - Ad-hoc boundary usage in a workspace may not be accounted for e.g. if
+//     the boundary command is invoked directly with the --log-proxy-socket-path
+//     flag set to something other than the Workspace agent server.
+//
+// Implementation:
+//
+// The Tracker maintains sets of unique workspace IDs and user IDs, plus request
+// counters. When boundary logs are reported, Track() adds the IDs to the sets
+// and increments request counters.
+//
+// FlushToDB() writes stats to the database only when there's been new activity
+// since the last flush. This prevents stale data from being written after a
+// telemetry reset when no new usage occurred. Stats accumulate in memory
+// throughout the telemetry period.
+//
+// A new period is detected when the upsert results in an INSERT (meaning
+// telemetry deleted the replica's row). At that point, all in-memory stats are
+// reset so they only count usage within the new period.
+//
+// Below is a sequence diagram showing the flow of boundary usage tracking.
