* Cleanup llama.cpp and use api key when configured
* don't report auto-populated object and audio filters as camera overrides
* derive stale replay cameras from bounded directory listings to avoid scanning all clips at startup
* fix tests
* add -vaapi_device to the birdseye vaapi encode preset so hwupload can initialize on ffmpeg 8
