AI Summary: Refactor the `generate_vocabulary` function in `app/main.py` to improve API efficiency by reducing unnecessary AI calls. The task involves checking if a user's input word (or its AI-corrected version) already exists in the local JSON storage before calling the Google Gemini API. If a match is found, return the stored data instead of making another API call. Consider adding test cases.

AI Summary: Update the project's README file to reflect the correct AI model name used in the code (gemini-2.0-flash-exp) instead of the outdated name (Google Gemini 2.5 Flash). This ensures consistency between the documentation and the actual implementation.
