Subject: Add cgit web interface for browsing repos

Adds cgit as a web frontend for browsing git repositories. Visiting the
base domain now shows a cgit repo index with trees, commits, diffs, and
blame views. Public repos (marked with git-daemon-export-ok) are browsable
and cloneable over HTTPS.

- Install cgit during host init
- Configure cgit with dark theme and base domain integration
- Add cgit CGI handler to base domain Caddyfile
- Update README to emphasize git-centric workflow with cgit frontend
