- Added configuration options for NVIDIA Nemotron API key, model, and base URL. - Refactored badword detection to utilize NVIDIA API, with a fallback to a local badword list. - Updated moderation functions to handle asynchronous operations for text evidence generation. - Removed dependency on the `indonesian-badwords` package and implemented custom detection logic. - Enhanced tests to accommodate asynchronous behavior and validate new detection methods.
