Handle stdout errors in StdioServerTransport instead of crashing the process. When a stdio client disconnects, the server's next write fails with EPIPE, and because nothing listened for 'error' on stdout that became an unhandled 'error' event, which takes the whole
Node process down. The transport now listens for it, reports it through onerror, and closes itself, so a client that goes away ends the session rather than killing the server.
send() no longer waits for a 'drain' event that a destroyed stream can never emit. It settles from an error listener armed before the write and removes both listeners on every exit path, so a write that fails rejects with the underlying error instead of leaving the promise
pending, and send() after close() rejects rather than writing to a stream the transport has let go of. close() is idempotent too, so an error-triggered close followed by an explicit one fires onclose once.
This backports the fix that shipped for the v2 line, so both lines now behave the same way on a disconnecting client.
