// Package agent owns the in-process flock-agent runtime. The agent is a
// single Linux DaemonSet pod per node and holds:
//
//   - the durable per-node allocation file at /var/lib/flock/allocations.json
//     (see Store in state.go),
//   - an in-memory IPAM seeded from NodeConfig CIDRs and reconciled against
//     the allocation file at startup (see ipam.go),
//   - dynamic informers watching the per-node NodeConfig CR (nodeconfig.go)
//     and the local-node Pod set (podinfo.go),
//   - an RPC server speaking to the lightweight CNI plugin binary
//     (cmd/flock and pkg/cni), so kubelet's CNI invocations are answered by
//     a long-lived process rather than spinning up a fresh binary per ADD,
//   - the BirdManager that renders bird.conf and triggers `birdc reload`
//     on changes (bird.go), and
//   - the AnycastReconciler that programs per-pod /128 and /32 host routes
//     gated on Pod readiness (anycast_linux.go).
//
// The package is split between platform-specific files (anycast_linux.go,
// netns_linux.go, runtime_linux.go) and stub files used on non-Linux build
// hosts so the rest of the package — IPAM, parsing, store, RPC plumbing —
// stays unit-testable on macOS and Windows CI.
