baekenough c39e9349dc feat(html-presentation): HTML 발표자료 생성 스킬 추가
슬라이드 콘텐츠만 AI가 작성하면 키보드 네비, 사이드 네비, 풀스크린
no-scroll이 보장되는 단일 HTML 발표자료(PPT 대체)를 생성하는 스킬입니다.

엔진(불변) + 콘텐츠(AI 작성) 엄격 분리:
- engine/engine.css (~600줄), engine/engine.js (~290줄) 불변
- 8개 레이아웃 카탈로그(cover, section, bullets, two-col, statement,
  image, code, end)와 DOM 계약
- 데모 인덱스: https://samples-weld.vercel.app/
- 데모 1 (라이트): https://samples-weld.vercel.app/ai-agent-trends-2026/index.html
- 데모 2 (다크):   https://samples-weld.vercel.app/hermes-agent/index.html

- SKILL.md 프론트매터: license MIT, category utility, locale ko-KR, phase v1
- 외부 의존성: Pretendard·JetBrains Mono·highlight.js CDN만 (오프라인 시 fallback)
- 두 자급형 샘플 덱 포함
