✨ feat(manalink): add PWA support and rebrand Matrix client

- Rename "Mana Matrix" to "Manalink" (bridge metaphor)
- Add PWA manifest with app icons and shortcuts
- Configure Service Worker with Workbox caching strategies
- Add iOS/Android meta tags for installability
- Create bridge-themed SVG favicon
- Add icon generation script (sharp)

PWA features:
- Installable on iOS/Android homescreen
- Offline caching (NetworkFirst for API, CacheFirst for assets)
- App shortcuts for "New Chat"
- Auto-updating Service Worker
