Files backend: release-name parser, video-only scanner, folder store, mpv thumbnails
lib/src/files/ for the 1.0 Files source (UI comes with the library round; ARCHITECTURE gets its section then): - parseReleaseName: series/season/episode/group/year/extras from release names (fansub, scene, batch, NCOP/OVA markers); seriesKey for grouping. - scanFolder (isolate): videos only, samples/trailers and other files counted as hidden, sidecar subtitles paired by name (+ language/flag suffixes), 20 000-file cap; groupBySeries -> series + loose videos. - FolderStore: watched folders and recent files in Hive, as signals. - thumbnailFor: a 480 px JPEG at 25% via a hidden mpv player (screenshot-to-file, vo=null), cached by path+size+mtime, 2 at a time, cancellable, never throws. No ffmpeg needed (Windows ships only libmpv). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
