feat(pwa): add Progressive Web App support with iOS compatibility
- Install vite-plugin-pwa and workbox-window for PWA functionality - Configure Vite with full PWA manifest (name, icons, theme, display) - Add service worker caching for static assets only (no API cache) - Create app icons (192x192, 512x512, apple-touch-icon) - Generate iOS splash screens for multiple device sizes - Add iOS-specific meta tags (apple-mobile-web-app-capable, etc.) - Implement InstallPWA component with dual platform support: - Android/Chrome: beforeinstallprompt event with custom UI - iOS Safari: manual installation instructions with icons - Add dismissal logic with 7-day localStorage persistence - Update documentation to reflect 90% project completion PWA implementation focuses on installability and static asset caching while avoiding offline API cache (WebRTC requires active connection).
