Donavan Fritz 759ed21b37 M1.5: NodeConfig dynamic informer + RBAC
Build flock Image / build (push) Has been cancelled
Details 
Agent now watches nodeconfigs.flock.fritzlab.net via a client-go dynamic
informer, filters events to its own node name, and caches the typed
NodeConfig in memory (NodeConfigCache, atomic pointer). M2's IPAM will
read from that cache.

- pkg/agent/nodeconfig.go: informer + JSON-round-trip decode (avoids
  hand-written DeepCopy + scheme registration for this small a use).
- pkg/agent/server.go: starts the informer goroutine; Run terminates if
  the informer returns.
- pkg/api/v1alpha1: switch placeholder TypeMeta/ObjectMeta to metav1.
- deploy/rbac: get/list/watch on nodeconfigs.
- cmd/flock-agent: --kubeconfig flag for out-of-cluster runs (tests).

Satisfies M1 verified-by: "kubectl apply NodeConfig; agent logs read it".

Donavan Fritz e0ae98ad6c ci: move go test into Dockerfile build stage
Build flock Image / build (push) Has been cancelled
Details 
The runner runs jobs via act + DinD; `docker run -v "$PWD:/src"` from
inside the job container mounts the runner-job filesystem, not the
docker daemon's host fs, so the mount appears empty and `go test ./...`
fails with "directory prefix . does not contain main module".

Run tests in the same container that builds — same workspace, no mount.

Donavan Fritz 20f47916af flock M1 scaffold: CNI plugin + agent + NodeConfig CRD
Build flock Image / build (push) Has been cancelled
Details 
- cmd/flock + cmd/flock-agent: build cleanly; CNI ADD/DEL/CHECK return
  ErrInternal stubs until M2; agent boots, opens unix socket, logs JSON.
- pkg/agent/state.go: durable allocations.json (atomic write + fsync +
  parent fsync); pending/committed lifecycle. Tests cover round-trip,
  replace-by-cid, version mismatch, no-leak-on-tmp.
- pkg/embed/suffix.go: ip-algo IID embedding. Tests cover the /48-/96
  nibble distribution table from the design doc, determinism, prefix
  preservation, N-nibble isolation, digest-vs-fallback divergence.
- pkg/api/v1alpha1: minimal NodeConfig types (no controller-runtime yet).
- deploy/: NodeConfig CRD, empty ServiceAccount/ClusterRole, DaemonSet
  pinned to flock.fritzlab.net/agent="" label so it only runs on opted-in
  nodes.
- .gitea/workflows/main.yaml + Dockerfile: build + push to
  code.fritzlab.net/fritzlab/flock; runs go test in CI.

Design doc: dfritzlab/k8s-manager/dfritz-cni.md.
