Design for mounting a Streamable HTTP MCP server inside the host-agent
process so Hermes Agent (or any MCP client) can drive devices directly.
Reuses the existing console FastAPI + uvicorn on port 8765, adds bearer-
token auth, per-device session-level locks with 60s TTL, and cloud
coordination via a new heartbeat field. Cloud scheduler skips devices
reported as MCP-busy.
