Generator-Skeleton (Phase 1): static HTML + watchdog + HTTP server

Replaces obv-Fork. New architecture:
- Python watchdog observes /home/admin/my-karpathy-wiki/
- On .md change → regenerate single HTML + update index
- On startup → full regen + tree.json/graph.json/tags.json/backlinks.json
- HTTP server on 127.0.0.1:8765 + tailscale proxy
- 265 static HTML pages with full Markdown rendering
- WikiLink resolution: [[entity]] → <a href='/path/entity.html'>
- Frontmatter as styled card (type, status, updated, sources)
- TOC auto-generated via markdown.extensions.toc
- PWA manifest for native-feeling install
- data.js with all metadata for offline use

Touch-first design (CSS+JS for tree/graph/search) follows in Phase 2.
