feat: redesign landing page with full feature showcase

Replace minimal 3-card landing page with comprehensive feature
presentation matching the rApp ecosystem style:

- Hero with ecosystem badge and gradient accents
- 4 core feature cards (GPS, navigation, meeting points, privacy)
- 6 differentiator cards (c3nav, pinging, Google import, PWA, QR, CRDT)
- How It Works steps
- Use case cards (festivals, city exploration, group coordination)
- Technical highlights grid (MapLibre, OSRM, c3nav, Automerge, etc.)
- Preserved existing Get Started form and room join flow
