Rename the business-layer concept from "Device ID" to "Hub ID" for
better user comprehension. The underlying network transport layer
still uses deviceId — Hub ID is passed as the deviceId value.
- Rename device.ts → hub-identity.ts, getDeviceId → getHubId
- Storage file: ~/.super-multica/device-id → ~/.super-multica/hub-id
- Hub property: deviceId → hubId
- API response field: deviceId → hubId
- Console UI label: "Device ID" → "Hub ID"

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
