Implement complete Docker Compose CI/CD setup with optimized builds

- Add multi-stage Dockerfile with dependency caching for both frontend and backend
- Implement Docker Compose configuration with separate frontend/backend services
- Configure Caddy as reverse proxy with proper WASM and static file serving
- Add volume mounting for frontend assets shared between containers
- Optimize build process with staged compilation and workspace handling
- Add debug logging and WASM initialization tracking for production deployment
- Update README with project motivation and "vibe coded" disclaimer

 # Modern CalDAV Web Client
 
+>[!WARNING]
+>This project was entirely vibe coded. It's my first attempt vibe coding anything, but I just sat down one day and realized this was something I've wanted to build for many years, but would just take way too long. With AI, I've been able to lay out the majority  of the app in one long weekend. So proceed at your own risk, but I actually think the app is pretty solid.
