Bearer-auth REST endpoints for humans, scripts, bots — anyone without
browser-side ed25519. Same key model as broker WS, scoped by capability
and optional topic whitelist.
Endpoints (v0.2.0 minimum):
- POST /v1/messages
- GET /v1/topics
- GET /v1/topics/:name/messages (limit, before cursor)
- GET /v1/peers
Auth: Authorization: Bearer cm_<secret>. Middleware verifies prefix +
SHA-256 hash with constant-time compare; capability + topic-scope
asserted per route. Cross-mesh isolation: every endpoint scopes to
apiKey.meshId.
Live delivery: writes to messageQueue + topic_message; broker's
existing pendingTimer drains and pushes to live peers. Real-time
push from REST writes is a follow-up.
