feat: add external subtitle file detection with language parsing and cache invalidation on subtitle changes

Browse Source 
Add EXTERNAL_SUBTITLE_EXTENSIONS set with common subtitle formats (.srt, .ass, .ssa, .vtt, .sub, .idx, .sup). Add external_subtitle_files() to glob subtitle files matching media stem and external_subtitle_languages() to parse language codes from filenames (de/deu/ger/german/deutsch, en/eng/english, fr/fra/fre/french/französisch, es/spa/spanish/spanisch, it/ita/italian/italienisch).

Update run_ffprobe() to merge external subtitle
