Closes #32064
PR #31975 made child process stdio streams into Socket instances backed by Pipe → StreamResource. When libraries like esbuild call
child.unref()/stdout.unref()to signal the event loop should be free to exit, the call chain was Socket.unref() → Pipe.unref() → only unrefs#listener(null for non-server pipes) → StreamResource never gets unref'd → process hangs.With this fix, Pipe.unref() also propagates to the stream in
[kStreamBaseField], so esbuild's unref calls reach the StreamResource and the event loop can exit properly.
