Closing a web console while the node kept streaming output crashed the ws_console/vnc_console handlers with an uncaught WebSocketDisconnect from the compute-to-client send path (only the opposite direction was guarded), producing a full ASGI traceback on every console close. Restructure both endpoints as symmetric forwarding tasks managed with asyncio.wait(FIRST_COMPLETED): exceptions from either direction are collected as task exceptions, the peer task is cancelled, the compute WebSocket is closed, and the client is notified. The receive loops now close and log on every exit path instead of only in the exception branch. Tests patch the in-memory ASGI transport to deliver a conformant websocket.disconnect on client close (it sends a non-conformant websocket.close that starlette receive() rejects).
