feat: add VITE_APP_MODE environment variable support

- Introduced VITE_APP_MODE variable in multiple files to manage application modes.
- Updated dev.mjs and docker-compose.dev.yml to set different modes for development.
- Enhanced type definitions in vite-env.d.ts to include VITE_APP_MODE options.
- Modified AutomakerLogo component to display version suffix based on the current app mode.
- Improved OS detection logic in use-os-detection.ts to utilize Electron's platform information.
- Updated ElectronAPI interface to expose platform information.

These changes provide better control over application behavior based on the mode, enhancing the development experience.
