* fix(#2686): review-fix agent now uses git worktree for isolation
The gsd-code-fixer agent operated directly against the main working tree,
racing any concurrent foreground session for HEAD, the index, and on-disk
files. Added a setup_worktree step (git worktree add /tmp/sv-N-reviewfix
HEAD) as the first action before any file operations, with unconditional
git worktree remove cleanup on exit. Mirrors the pattern used by all other
GSD per-issue agents.

* fix(#2686): address CodeRabbit review — mktemp unique path, branch-aware worktree, tighten test assertions
- Use mktemp -d for unique worktree path (prevents concurrent-run collision)
- Resolve branch via git branch --show-current before worktree add (prevents detached HEAD)
- Error-and-exit on worktree add failure instead of force-removing shared path
- Test: use .exec().index for checkout position (not indexOf on match string)
- Test: match gsd-sdk query commit as well as git commit for ordering assertion
- Test: tighten /tmp path assertion to require actual /tmp/sv- assignment
