- Introduced a new `LOG_LEVEL` configuration option in the `.env.example` file to allow users to set the logging level (DEBUG, INFO, WARNING, ERROR). - Updated the `Settings` class to include the `log_level` attribute, normalizing its value to ensure valid logging levels are used. - Modified the logging setup in `run.py` to utilize the configured log level, enhancing flexibility in log management. - Enhanced the Mini App to include the logging level in the JavaScript configuration, allowing for consistent logging behavior across the application. - Added a new `logger.js` module for frontend logging, implementing level-based filtering and console delegation. - Included unit tests for the new logger functionality to ensure proper behavior and level handling.
