Stopping a stream to an RTMP receiver crashed the app with SIGSEGV inside
LiveStreamManager.stopStream (Mavic Pro, 2026-10-22). stopStream returns at
once and frees the native streamer on an SDK thread, while the bridge kept
reading bitrate/fps/time through native getters from its poll and right
after the stop. The poll now ends first, nothing reads those getters while
stopping, and the bridge waits for the SDK to report the stream stopped.
