connect() used connect_async with no WebSocketConfig and next_event awaited the socket with no deadline, so a stalled server hung the feed forever and an oversized message could force an unbounded allocation. connect() now passes a WebSocketConfig capping message/frame size, and next_event wraps the read in a 300s tokio timeout (well above Binance's ~3-minute ping), surfacing a stall as the new Error::Timeout.
