refactor: streamline error handling and logging in ModernAiProvider

- Commented out the try-catch block in the `ModernAiProvider` class to simplify the code structure.
- Enhanced readability by removing unnecessary error logging while maintaining the core functionality of the AI processing flow.
- Updated `messageThunk` to incorporate an abort controller for improved request management during message processing.
