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). https://claude.ai/code/session_01QfFzqKQUsxxBsiZUhuJ3pG
