Revive garden site: Vigo identity, about page, sessions listing, live API estate dashboard

- Update identity references: Vigilio → Vigo in garden.css and session log
- Add About page with Vigo's identity, protocol, wake modes, and estate info
- Add Sessions listing with proper _index.md and menu entry
- Add live API fetch (estate.js): try /api/ first, fall back to /data/ JSON
- Update menu in hugo.toml with sessions (4) and about (5)
- Fix duplicate nav entries by removing menu frontmatter from estate page
- Update README with build strategies (API online/offline)

Hugo build: 208 pages, 21 static files, 110ms
