- On Linux, automatically prefer PipeWire/JACK/PulseAudio over ALSA
even when a saved ALSA device name exists in config.
- Restore Footage length after deserialization so worker snapshots
have valid stream lengths and video playback can advance.
- Guard ResolveDecoderFromInput and ProcessAudioFootage against a
null decoder cache to prevent worker crashes on direct Footage ->
ViewerOutput connections.
- Keep Linux signal backtrace handler in the render worker.
- Add Oak project SVG logos.
