test: GitVcsDriverCore 'keeps complete stats for files beyond the combined patch limit' is flaky #646

What happens

apps/server/src/vcs/GitVcsDriverCore.test.ts › GitVcsDriver core integration › review diff previews › keeps complete stats for files beyond the combined patch limit failed once in CI and passed on re-run with no change.

• Run: https://github.com/pylon-code/pylon/actions/runs/35374265950 (job "Test Server 2"), PR feat(delegation): skip the wake for a completion the parent already read #639, which does not touch vcs/.
• Failure: AssertionError: expected [ …(2) ] to deeply equal [ { path: 'a-large.txt', …(3) }, …(2) ], so the result held two entries where three were expected.
• Rest of that shard: 2377 passed.

Guess, unverified

The test builds a real git repository and reads diff stats past a size limit. An entry going missing suggests ordering or timing in how the large file's stats are collected, rather than a logic error.
