WIP: VM-756 Phase 1 — MCP auto-connect with deterministic device ID

Paused: gateway needs device-to-user linking (VMD-124) before this
can be properly completed.

What's here:

- deviceId + name fields in WebSocket ready message
- FastMCP lifespan hook for Connect auto-start on MCP boot
- 13 tests for device ID generation
