- Update CloudronManifest.json to use modern format with proper ID, health check, and metadata
- Fix Dockerfile to follow Cloudron conventions (/app/code, /app/data structure)
- Correct Rathole configuration format (default_token instead of token, add services section)
- Fix start.sh to use proper --server flag syntax
- Add health check endpoint on port 8080
- Create comprehensive build notes documentation
- Successfully build and test package - both ports 2333 (Rathole) and 8080 (health) working
