feat: Git recency bonuses - #841
Conversation
📝 WalkthroughWalkthroughAdds configurable Git recency ranking. Recent branch commits add per-file score bonuses. The change updates indexing, scoring, integrations, UI output, tests, snapshots, and documentation. ChangesGit recency ranking
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to Git recency can rank files based on commits outside the active branch and can apply stale Git-derived ranking data after picker changes. These ranking and state-consistency issues should be resolved before merging. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)
✅ Passed checks (4 passed)

Normalize base_path before deriving subdir.
On Unix, FilePicker::new preserves .., while git_recency::compute returns repository-relative paths. For /repo/sub/.., strip_prefix produces sub/..; the resulting sub/../ prefix matches no Git path, so all recency scores stay zero. Normalize base_path lexically and add a .. regression test.

Treat this as a breaking API change. fff-search exposes FilePickerOptions with public fields. Adding required git_recency makes existing downstream struct literals fail to compile. Update supported consumers and publish this in a breaking release.

Guard refresh_git_status results with picker identity.
refresh_git_status captures A’s Git data, then reindex can publish B before the write lock is reacquired. The method can then apply A’s status and relative-path recency results to B. Use a generation or equivalent picker-identity check and discard both results on mismatch. A root or base-path check alone is insufficient.

Handle merge_base == head as an empty branch window.
When a non-base branch points at the merge base, the revwalk can include base-branch commits and assign stale recency bonuses. Return an empty score map in this case.
