feat: add Wails runtime library and initial application setup

- Created package.json for Wails JavaScript runtime library.
- Added TypeScript definitions for runtime functions.
- Implemented runtime.js with event handling and logging functions.
- Initialized Go module with dependencies for Wails and other libraries.
- Added main.go for application entry point and asset embedding.
- Configured wails.json for application settings and build commands.
