Follow-up to cdf7149 -- the page deletion committed but these three
fixes didn't (git add errored on the already-removed pathspec, same
mistake as before). Repoints home.md's Schnellnavigation, the sidebar,
and setup.md's intro note at CLAUDE.md in the main repo instead of the
now-gone page.
Complete documentation overhaul with professional guides
- Rewrite home.md as welcoming entry point with clear value proposition
- Create comprehensive setup.md with step-by-step installation guide
- Include phased deployment strategy (Traefik → Headscale → Services)
- Add Cloudflare DNS challenge setup and troubleshooting section
- Document complete three-machine architecture deployment process
