Implement Hub that auto-connects to Gateway, manages agents via REST API,
and routes WebSocket messages to agents by payload.agentId with echo responses
sent back to the original sender.
- Add Hub with GatewayClient auto-connect, agent CRUD, and message routing
- Add Console (NestJS) with REST API and static pages (management + demo client)
- Switch Gateway registration from explicit event to query-based on connect
- Remove deprecated types (RegisterPayload, metadata, SendMessagePayload)
- Add @nestjs/serve-static for serving console UI
