        WebSocket endpoint for data plane connections. Data planes connect here
        to register with the control plane, send heartbeats, and receive artifact
        notifications.

        **Protocol:**
        1. Connect with WebSocket upgrade
        2. Send `register` message with project_id and api_key
        3. Receive `registered` confirmation with data_plane_id
        4. Send periodic `heartbeat` messages (every 30 seconds)
        5. Receive `artifact_available` when new deployments are triggered

        **Messages (Data Plane → Control Plane):**
        - `{"type": "register", "project_id": "uuid", "api_key": "bbk_...", "name": "optional-name"}`
        - `{"type": "heartbeat", "artifact_id": "uuid"}`

        **Messages (Control Plane → Data Plane):**
        - `{"type": "registered", "data_plane_id": "uuid", "heartbeat_interval_secs": 30}`
        - `{"type": "artifact_available", "artifact_id": "uuid", "download_url": "/artifacts/{id}/download", "sha256": "..."}`
