- Fixed `FastAPIWebsocketTransport` intermittently hanging on shutdown when the remote side (e.g. Twilio) disconnects while audio is being sent. A race condition between the send and receive paths could cause the `on_client_disconnected` callback to be skipped, leaving the pipeline waiting for a disconnect signal that never came.
