Introduces a fourth controller that watches GitRepository resources and
polls their remotes via git ls-remote on a configurable per-repo interval
(spec.pollInterval, defaulting to 30s). It auto-creates, updates, and
deletes GitBranch CRDs to reflect the actual state of the remote,
enabling fast detection of external pushes to trigger downstream sync.
Key changes:
- Add PollInterval field to GitRepositorySpec
- New pkg/reconciler/repowatcher with controller and reconciler
- New cmd/repo-watcher-controller binary
- CRD manifest updated for pollInterval
- Deployment manifest for the new controller
- Unit tests for ref filtering, naming, and poll interval logic
- CLAUDE.md updated with new controller docs and Go module workaround

Build a complete Kubernetes control plane for Git operations using Knative's
pkg framework, go-git for in-memory Git operations, and ko for builds.
Architecture:
- 4 CRDs: GitRepository, GitBranch, GitPushTransaction, GitRepoSync
- Push controller: atomic Git push via go-git with CAS (compare-and-swap)
- Sync controller: two-way sync with in-memory merge base calculation
- Resolver controller: automated 3-way merge for conflicted syncs
- In-cluster Gitea server for backing storage
- Full RBAC, ko-based deployments, and code-gen scaffolding
Note: go.sum needs generation via `go mod tidy` in an environment with
full internet access (knative.dev/pkg v0.0.0-20250520014526-44579e9ce5ed).
