Two follow-up nits from PR #2211 review:
- Rename the package-local `repoCache` interface to `repoCacheBackend`
so the field declaration `repoCache repoCacheBackend` no longer shadows
its own type name.
- Bump the `/health`-must-respond timeout in
`TestHealthHandlerRespondsWhileTaskRepoLookupWaits` from 200ms to 1s.
The regression case blocks indefinitely on the old code, so a 1s
upper bound still fail-fast detects it while leaving headroom for
loaded CI runners.
