conductor(video_analysis_campaign): Initialize umbrella track + 12 child + 1 synthesis scaffold

Pass 1 of 3 user research campaign (12 videos, 5 clusters).
- Umbrella: spec.md (full design), plan.md, metadata.json, state.toml, README.md
- Multi-pass framing (Pass 2 de-obfuscation, Pass 3 projection)
- Lossless preservation directive (1000-10000 LOC per video report target)
- Tooling prerequisites: yt-dlp, cv2, imagehash install in repo venv
- 5 reusable scripts to live in scripts/video_analysis/ (TDD)
- 12 children + 1 synthesis = 14 folders total
