    WebSocket client transport for MCP, symmetrical to the server version.

    Connects to 'url' using the 'mcp' subprotocol, then yields:
        (read_stream, write_stream)

    - read_stream: As you read from this stream, you'll receive either valid
      JSONRPCMessage objects or Exception objects (when validation fails).
    - write_stream: Write JSONRPCMessage objects to this stream to send them
      over the WebSocket to the server.
