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

- Extract triplicated splitKey into shared pkg/reconciler/internal package
using strings.Cut and removing the unnecessary error return
- Fix resolver merge bug: attemptMerge was using treeA.Hash as the merge
commit tree, silently dropping all of branch B's changes. Now builds a
proper merged tree that applies B's non-conflicting changes onto A's tree
- Replace hand-rolled nestedFieldNoCopy/unstructuredNestedStringMap with
k8s.io/apimachinery's unstructured.NestedStringMap stdlib equivalent
- Hoist branch listing out of per-refspec loop in updateBranches to avoid
redundant API calls
- Add not-found handling in all three reconcilers so deleted resources
don't cause infinite requeue loops
- Fix client.Get() to use checked type assertion with a clear panic message
instead of an opaque nil-pointer dereference
- Remove dead code: unused addDefaultingFuncs wrapper, unused context
injection in push controller setup

Add unit tests for all packages that previously had zero test coverage:
- pkg/apis/git/v1alpha1: defaults, deepcopy, scheme registration, constants
- pkg/client: toUnstructured/fromUnstructured round-trips, context injection
- pkg/reconciler/push: splitKey, nestedFieldNoCopy, unstructuredNestedStringMap, base64 decoding
- pkg/reconciler/sync: splitKey
- pkg/reconciler/resolver: splitKey, changeName
Add e2e test exercising the sync controller:
- Creates second Gitea repo and GitRepository CR
- Creates GitBranch CRs with headCommit set via status subresource patch
- Creates GitRepoSync CR and verifies the sync controller processes it

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).
