v0.0.10: Progressive Web App (PWA)

- Web manifest (standalone mode, theme, icon)
- Service worker: caches shell (HTML, WASM, icon) for offline
- SVG app icon (chat bubble with encryption indicator)
- iOS meta tags: apple-mobile-web-app-capable, status bar style
- Android: beforeinstallprompt → /install command
- Offline fallback: loads cached shell, shows reconnecting state
- Cache versioning with automatic old cache cleanup
