M2 plumbing: CNI ↔ agent JSON RPC over unix socket

Locks the wire format between /opt/cni/bin/flock and flock-agent. ADD
returns a CNI Result, DEL returns success/error, CHECK returns
success/error. Connection-per-RPC, newline-delimited JSON.

- pkg/cni/rpc.go: shared Op + Request + Response + framed encode/decode.
- pkg/cni/rpc_client.go: net.Dial + EncodeRequest + DecodeResponse;
  rpcSocket overridable for tests.
- pkg/cni/plugin.go: real implementations of CmdAdd/Del/Check that call
  through, mapping agent errors to types.Error.
- pkg/agent/rpc.go: rpcServer with swappable AddHandler/DelHandler/
  CheckHandler (defaults: not-implemented for ADD; idempotent-no-op for
  DEL/CHECK so kubelet teardown of a never-ADDed pod doesn't fail).
- pkg/agent/server.go: replaces the M1 accept-and-close placeholder
  with rpcServer.serve(ctx, listener); listener closes on ctx cancel.

Tests cover: Request/Response JSON roundtrip, end-to-end client →
unix-socket → fake server, agent error → CNI types.Error mapping.

ADD remains "not implemented" until netlink + IPAM wire-up — the agent
returns an error and kubelet will fail pod sandbox creation IF a node
were configured to use this CNI. host001's CNI plane is still 100%
Calico, so this changes nothing observable on the cluster.
