- Added optional logger parameter to various classes including `BaseDataCollector`, `CollectorManager`, `RealTimeCandleProcessor`, and `BatchCandleProcessor` to support conditional logging.
- Implemented error-only logging mode, allowing components to log only error and critical messages when specified.
- Updated logging calls to utilize new helper methods for improved readability and maintainability.
- Enhanced documentation to include details on the new logging system and its usage across components.
- Ensured that child components inherit the logger from their parent components for consistent logging behavior.
