VSCode's multi-diff editor also appends its own " (N files)" count to the title we pass. The title assertion now verifies the label starts with our human-scannable comparison title AND ends with the changed-file count, which is strictly stronger than the previous exact-match and reflects exactly what the user sees.

Rewrite GitRepo.test.ts to guard the single recorded call via `.at(0)` + assert, and assert whole-result equality; GitRunner.test.ts drops the unused log-event field. No coverage change (still 153 unit + 41 E2E, threshold 95.3).
