Add Images section — hub + 4 collection galleries, wire nav star

- Images/images.html: hub page linking all 4 collections
- Images/wayback.html, nomad-soul.html, myster-wizzard.html, exopraxist.html: collection galleries
- 429 thumbnails (360px) committed across 4 collections
- Gallery renders from baked filename arrays (no on-load fetch)
- Lightbox lazy-fetches FileBrowser for full-res on click, falls back to thumbnail
- .gitignore: allow Images/*/thumbnails/, anchor /GEMINI.md to root only, add .venv/
- index.html: wire Images star node to Images/images.html
