Skill-字幕

Separate subtitle timing from subtitle appearance:

• Let ra-audio-to-subtitles own ASR, phrase grouping, timestamps, SRT/VTT, and caption-qc.json.
• Let this skill own typography, panel geometry, fixed anchoring, preview, overlay rendering, burn-in, and render QC.
• Never estimate production timing from character count, scene duration, or TTS segment duration.
