refactor: Flatten directory structure
Move project files from uzdb/ subdirectory to root directory for cleaner project structure.
Changes:
- Move frontend/ to root
- Move internal/ to root
- Move build/ to root
- Move all config files (go.mod, wails.json, etc.) to root
- Remove redundant uzdb/ subdirectory nesting
Project structure is now:
├── frontend/ # React application
├── internal/ # Go backend
├── build/ # Wails build assets
├── doc/ # Design documentation
├── main.go # Entry point
└── ...
