Subject: [PATCH] v0.0.10: Progressive Web App (PWA)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 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
