- Changed provider delta input comparisons in `buildResponsesDeltaInput` to use `Bun.deepEquals` instead of stringified JSON checks.
- Updated session message diffing to return early on length changes and compare normalized entries with deep equality.
- Replaced JSON-string assertions in the issue-966 repro test with `Bun.deepEquals` for stable equality checks.
runSplitCommit reset the index and then re-staged each split via
git.stage.hunks, but stage.hunks builds its file map from the current
diff. After the reset, newly created files were untracked again and
absent from that map, throwing "No diff found for <path>" mid-split.
Preserve the original staged diff so new files remain locatable
through every split iteration.
Fixes#966
