feat(skills): product-launch-video skill + consolidate motion knowledge into hyperframes-animation (#1745)

* feat(skills): product-launch-video + consolidate motion knowledge into hyperframes-animation

- Add the product-launch-video skill: shot-sequence architecture where each
  visual frame is a time-coded shot sequence picked from a blueprint menu and
  paced to the voiceover (anti-PowerPoint). Includes the frame-worker sub-agent,
  story/visual/motion-design references, and audio/captions/transitions/
  stage-assets/assemble-index scripts.
- Consolidate motion knowledge in hyperframes-animation as the single source of
  truth: promote the updated atomic rules (31 -> 36) and rename product-launch-
  video's archetypes into hyperframes-animation blueprints (13 -> 15, replacing
  the old set). product-launch-video, faceless-explainer, and pr-to-video now
  reference them via ../hyperframes-animation/{rules-index,blueprints-index}.md
  and the rules/blueprints dirs. Fixes the discrete-text-sequence broken links;
  blueprints no longer ship per-id runnable examples, so example references in
  the consumers were dropped.
- Default HeyGen TTS voice to Marcia (deterministic; was the API's first English
  voice, which drifts on catalog re-sort). Override with --voice.
- assemble-index pre-assembly frame guards: auto-repair a sub-comp root missing
  canvas dims; hard-fail on <video>/<audio> inside a sub-comp; hard-fail on a
  timed non-root element missing class="clip" or overlapping same-track clips.
- Lint/CLI: lint media inside sub-compositions as an error; stop false-positive
  caption layout/lint findings; contrast/layout-audit skip elements hidden by an
  invisible ancestor.

* fix(skills): clear CodeQL alerts in assemble-index.mjs

- script/style blanking regex now matches closing tags with trailing
  whitespace (</script >, </style >) — js/bad-tag-filter (high).
- drop the existsSync precheck before reading/repairing a frame file; read
  directly and handle ENOENT, removing the check->write TOCTOU window —
  js/file-system-race (high).

 - **Transforms only** — `scaleY` / `scaleX` / `clipPath`, never `width`/`height` tweens (runtime-forbidden).
