A frame hook ends an active film or export when the world is gone. The game
stops ticking at the title screen but keeps rendering, so an export used to
keep recording the title with its playback clock frozen (a sec=10 request
produced 3898 frames) and went on after re-entering the world. Session
cleanup runs once with WorldChange and cancels the capture.
Real short exports on a scratch home and world (pin 57f8b2853, API 29,
Metal): h264+AAC both 2.07 s with non-silent audio, reported frames equal
ffprobe nb_frames; cancel, SDK refusal, encoder failure and restart all
leave no capture running; 1920x1080 works. The engine still leaves
*.audio.raw and *.ffmpeg.log behind on an encoder error (game/film.rs).
