Cherry-pick of 995dbb4f (originally on feat/sfx-audio-search) into
feat/w2h-restructure-v3, now mergeable because main was just folded
into this branch and brought cloud/auth.
CLI (packages/cli/src/commands/sfx/):
- list / search / add / inspect
- analyze.ts (ffmpeg ebur128 + silencedetect, LUFS/peak/onset/tail
+ loudness sparkline + suggested trim)
- auth.ts (free HeyGen key opt-in instead of raw 401)
- catalog-manifest.ts (180 clips across 22 families, generated)
Skill docs:
- skills/hyperframes/references/sound-effects.md (the global model)
- skills/hyperframes/SKILL.md + beat-direction.md link sound-effects.md
- skills/website-to-hyperframes step-3/step-5 migrate off bundled SFX
onto catalog flow (incorporates session-13/16 prose: orchestrator
authoring stays out, landmines stay in)
- assets/sfx/ deleted (20 mp3 + manifest.json + CREDITS.md)
Cherry-pick conflicts resolved manually:
- step-3-storyboard.md SFX section: took catalog version
- step-5-build.md: kept our session-13/16 structure (landmines,
assembler-owned index.html), folded in commit's catalog-analysis
paragraph
- manifest.json: deleted per the commit's intent
