fix(subtitles): recover positioned ASS word spacing and drop control deb
- Recover Latin/romaji word spaces encoded only by positioned `\pos`/`\move` fragment gaps in ASS karaoke - Drop malformed ASS rotation-reset spacer lines and skip zero-duration metadata events - Dedupe duplicate lines across multiline primary/secondary cues, including full-width variants - Treat dense fragment-grid sign layouts as visual typesetting, not publishable text, during primary subtitle resolution
