Agent-node protocol DTOs (roadmap phase 67, Stage 3).
node/status lets any client ask which node is serving it and how the
connection is authorized. Locally-served app-servers answer with
served: false; agent-node servers fill the identity that is also
injected into initialize metadata. Enrollment and revocation are
deliberately CLI-only operations on the node host (they mutate the
node’s local trust store), not public app-server methods.
