Replace the Mosquitto/paho mesh transport with NATS JetStream KV: - mesh_wire.py: transport-agnostic registry (de)serialization (secret-stripped) - nats_client.py: async CastleNATSClient — registry in the castle-registry KV bucket, heartbeat liveness, delete-on-stop offline, watch-driven mesh state - rewire main/config/models/nodes; MeshStatus -> connected/nats_url - frontend MeshStatus + MeshPanel to the new fields - drop paho-mqtt/mqtt_client + _mqtt._tcp mDNS browse; add nats-py - keep the secret-stripping invariant; mDNS peer discovery retained Single-node verified; two-node parity pending the second node.
