Subject: add snonux static microblog generator

Full Go implementation with:
- txt/md/image/audio input processing, URL auto-linking in .txt files
- Paginated HTML output with Atom feed
- 11 visual themes: neon, terminal, synthwave, minimal, brutalist, paper,
  aurora, matrix, ocean, retro, glass (selectable via --theme flag)
- Keyboard navigation (j/k/arrows, Enter modal, h/l page nav)
- Shared nav templates (navhints, navmodal, navscript) across all themes
- Magefile build automation; integration test suite covering all themes
