Michael Ramos 472e17be3d feat: expandable diff context in code review (#247)
* feat: expandable diff context in code review (closes #243)

Switch from PatchDiff to FileDiff component from @pierre/diffs to enable
GitHub-style "show more lines" buttons between hunks. The library handles
all expansion UI when provided full file contents via oldLines/newLines.

- Add /api/file-content endpoint to serve old/new file content per diff type
- Add getFileContentsForDiff() helper with ref mapping for all diff types
- Parse patch client-side via getSingularPatch(), augment with file contents
- Update @pierre/diffs from 1.0.4 to 1.0.11 (scroll sync fix, no breaking changes)

* fix: upgrade @pierre/diffs to beta, re-parse patch with full file contents

The previous approach spread file content arrays onto a partial-mode
FileDiffMetadata, causing hunk index mismatches and Shiki decoration
errors. Now uses processFile() to re-parse the patch with oldFile/newFile
so hunk indices are computed against the full file (isPartial: false),
which is required for expansion to work correctly.

Also fixes a flash error on file switch by tagging fileContents with the
filePath they were fetched for, preventing stale contents from being
paired with the wrong patch during the render before useEffect fires.

- Upgrade @pierre/diffs from ^1.0.x to ^1.1.0-beta.19 in all workspaces
- Add test fixtures for disjoint hunks, deleted/renamed/new files

* fix: abort stale file-content fetches, validate path params

- Add AbortController to file-content fetch effect to cancel in-flight
  requests when switching files
- Reject path traversal (.. or absolute paths) on /api/file-content
- Document /api/file-content endpoint in CLAUDE.md
