Preserve persisted thread git info in resume (#13504)

## Summary
- ensure `thread.resume` reuses the stored `gitInfo` instead of
rebuilding it from the live working tree
- persist and apply thread git metadata through the resume flow and add
a regression test covering branch mismatch cases

## Testing
- Not run (not requested)
