Repair owned repository caches that are missing origin

[AntoineToussaint]

Observed production failure

Mind's real SWE-bench ingest-only production path delegates repository preparation to Codefly PrepareRepositoryCheckout. With the default shared Codefly-owned cache, a valid Git checkout can exist without an origin remote. Codefly accepts it as a repository at rev-parse --git-dir, then fails permanently at:

prepare repository checkout capability: resolve repository origin:
git remote get-url origin: error: No such remote 'origin'

This currently makes Mind TestSWEBenchIngestOnlyPerformanceSmoke fail before checkout/ingestion for django__django-11099. It reproduces unchanged on Mind main efadc4e0 with Codefly CLI v0.1.80.

Generic behavior needed

PrepareRepositoryCheckout owns this named cache projection and already repairs interrupted non-repositories. It should also recover a structurally valid owned cache whose origin is absent, using the typed request's authoritative RepositoryURL, then continue the normal fetch/revision/clean flow.

It must still fail closed when an existing origin points somewhere different; do not silently retarget a mismatched source. Cache/worktree safety and cancellation preservation must remain intact.

Acceptance

• A real repository cache with no origin is repaired through the production typed capability and resolves the requested revision.
• A cache with a mismatched existing origin still fails.
• Retry remains idempotent and leaves a clean checkout.
• No workaround or Git command is added to Mind.
