fix(repository): immediately re-clone on pull failure

[arnaud-dezandee]

Fix the git bundle flow to immediately re-clone and retry when a pull fails (e.g. after a force-push), instead of returning an error and deferring recovery to the next reconciliation cycle.

• Extract Bundle logic into bundleWithRetry(ref, isRetry) to support a single retry
• On pull failure, delete the local repo and recursively call bundleWithRetry with isRetry=true
• If the retry also fails, return a clear error instead of silently deferring

I did some more testing and this does not fix all issues I see on my deployment. Here is a log extract

Will try #783 and see if that solves it
