feat(cli,core): standalone transcribe command, transcript normalization, caption lint rules (#151)

* feat(cli,core): add standalone transcribe command, transcript normalization, and caption lint rules - Add `hyperframes transcribe` command for transcribing audio/video and importing existing transcripts (SRT, VTT, OpenAI Whisper API JSON, whisper.cpp JSON) - Add transcript format normalizer (normalize.ts) with auto-detection and conversion to standard [{text, start, end}] word arrays - Upgrade default whisper model from base.en to small.en for better accuracy - Add --model and --language flags to both `transcribe` and `init` commands - Extract shared patchCaptionHtml() to eliminate duplication between init.ts and transcribe.ts (init.ts reduced by ~55 lines) - Add 3 caption lint rules: caption_exit_missing_hard_kill, caption_text_overflow_risk, caption_container_relative_position - Update captions skill with model guide, format docs, music guidance, text overflow prevention, caption exit guarantee pattern - Expand captions skill trigger to cover lyrics, karaoke, lyric videos Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs(cli): add transcribe command and --model/--language flags to CLI docs Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * fix(cli): fix blank template lint issues - blank/index.html: remove data-start from video (was nested in timed parent), add class="clip" for initial hidden state - blank/captions.html: add max-width + overflow:hidden to prevent text clipping, add tl.set hard kill after exit tween to prevent stuck captions Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * docs: add lint-after-edit rule to repo and project CLAUDE.md Agents must run `npx hyperframes lint` after editing compositions. Also expand captions skill description in project template.
