This change fixes the white screen issue on Vercel by adding a check for the VITE_GEMINI_API_KEY. If the key is missing, it displays a clear error message instead of a blank page. It also improves the code's robustness by handling the missing key gracefully and documents the required environment variables in a new .env.example file.

This commit resolves an issue where the application would display a blank white screen when deployed without the required `VITE_GEMINI_API_KEY` environment variable.

The key changes are:
- Implemented a startup check in `App.tsx` to verify the presence of the API key. If the key is missing, an informative error screen is now rendered, instructing the user on how to configure it.
- Refactored `services/geminiService.ts` to initialize the Google Gemini client lazily. This prevents the application from crashing on load if the API key is not available.
- Simplified `vite.config.ts` by removing the custom `define` block and relying on Vite's standard `import.meta.env` mechanism for environment variables.
- Added a `.env.example` file to document the necessary environment variables for easier project setup.
