feat(site): add expand-context support to diff viewer

Add lazy per-file context expansion for local diffs. When viewing a diff in the Git panel, each file header shows an "Expand context" button. Clicking it fetches the full old (HEAD) and new (working tree) file contents via a new coderd proxy endpoint, re-parses the diff with @pierre/diffs processFile (which sets isPartial: false), and swaps in the enriched FileDiffMetadata. The library's native hunk separator expansion then takes over. Backend: - agent/agentgit: new GET /api/v0/git/show endpoint returning file contents at a git ref (with binary/size guards) - codersdk/workspacesdk: GitShowFile SDK method on AgentConn - coderd: new GET /api/experimental/chats/{chat}/file-content proxy endpoint that dials the agent for old (git show HEAD) or new (working tree read) file contents Frontend: - expandFileDiff utility wrapping processFile with oldFile/newFile - extractFilePatch utility to split multi-file diffs - DiffViewer: expansion state, ExpandContextButton, effectiveFiles overlay - LocalDiffPanel: wired to fetch via Promise.allSettled - Updated @pierre/diffs 1.1.0-beta.19 -> 1.1.7 - Replaced deprecated enableHoverUtility with enableGutterUtility

 - **Async findings.** When a finding mentions setState after unmount, unused cancellation signals, or missing error handling near an await: (1) find the setState or callback, (2) trace what renders or fires as a result, (3) ask "if this fires after the user navigated away, what do they see?" If the answer is "nothing" (a ref update, a console.log), it's P3. If the answer is "a dialog opens" or "state corrupts," upgrade. The severity depends on what's at the END of the async chain, not the start.
 - **Mechanism vs. consequence.** Reviewers describe findings using mechanism vocabulary ("unused parameter", "duplicated code", "test passes by coincidence"), not consequence vocabulary ("dialog opens in wrong view", "attacker can bypass check", "removing this code has no test to catch it"). The Contract Auditor and Structural Analyst tend to frame findings by consequence already — use their framing directly. For mechanism-framed findings from other reviewers, restate the consequence before accepting the severity. Consequences include UX bugs, security gaps, data corruption, and silent regressions — not just things users see on screen.
 - **Weak evidence.** Findings that assert a problem without demonstrating it. Downgrade or drop.
- **Unnecessary novelty.** New files, new naming patterns, new abstractions where the existing codebase already has a convention. If no reviewer flagged it but you see it, add it.
+- **Unnecessary novelty.** New files, new naming patterns, new abstractions where the existing codebase already has a convention. If no reviewer flagged it but you see it, add it. If a reviewer flagged it as an observation, evaluate whether it should be a finding.
 - **Scope creep.** Suggestions that go beyond reviewing what changed into redesigning what exists. Downgrade to P4.
 - **Structural alternatives.** One reviewer proposes a design that eliminates a documented tradeoff, while others have zero findings because the current approach "works." Don't discount this as an outlier or scope creep. A structural alternative that removes the need for a tradeoff can be the highest-value output of the review. Preserve it at its original severity — the author decides whether to adopt it, but they need enough signal to evaluate it.
 - **Pre-existing behavior.** "Pre-existing" doesn't erase severity. Check whether the PR introduced new code (comments, branches, error messages) that describes or depends on the pre-existing behavior incorrectly. The new code is in scope even when the underlying behavior isn't.
