UdpSocket bound on 0.0.0.0:9000

  ├── listener.rs   decode → throttle → emit Tauri events → frontend
  │
  └── sender.rs     encode PbEnvelope → send_to rover address
        ▲
        └── dummy.rs   generates fake packets for development

The socket is created once in service.rs, wrapped in an Arc, and shared between the listener and the sender/dummy so they all use the same bound port.
