Added:
- Added audio track metadata to playback decisions: responses now include an audioTracks array (id, label, language, codec, channels, default) built from the probed audio streams, so clients can surface and select audio without re-probing. The default track follows the preferred audio language when set, otherwise the first stream. Audio-track-aware codec selection now reads directly from the probed streams instead of the file's primary track.

Changed:
- Updated @better-auth/api-key, better-auth, @lucide/svelte, hls.js, kysely, svelte, and svelte-check dependencies.

Fixed:
- Fixed web playback stalling at the first HLS encode-window boundary (#175). Each encode window (4 x 16s segments) is a fresh FFmpeg process that input-seeks, which restarted media timestamps near zero for every window while the served VOD playlist declared a continuous timeline. HLS.js discarded the out-of-range segments and playback froze at ~1:04. Windows now apply -output_ts_offset matching their start time (and use -avoid_negative_ts make_non_negative, which preserves it) so segment timestamps stay continuous across windows, fixing playback from the start, after mid-playback seeks, and after resuming past the first window.
