Qingyu Wang 9d8a9adfe8 stream: fix pipeTo assert when writer is released during microtask ...

pipeTo defers each slow-path write to a microtask so it does not run
synchronously during enqueue(). A race allows the pipe to shut down and
release its writer after the write is scheduled but before it runs. The
deferred write then hits an ERR_INTERNAL_ASSERTION because
writer[[stream]] is undefined.

Skip the deferred write when shutdown has already started.
