- Introduced `example_complete_series_aggregation.py` to demonstrate time series aggregation, emitting candles even when no trades occur.
- Implemented `CompleteSeriesProcessor` extending `RealTimeCandleProcessor` to handle time-based candle emission and empty candle creation.
- Refactored `OKXCollector` to utilize the new repository pattern for database operations, enhancing modularity and maintainability.
- Updated database operations to centralize data handling through `DatabaseOperations`, improving error handling and logging.
- Enhanced documentation to include details on the new aggregation example and repository pattern implementation, ensuring clarity for users.
- Increased health check interval from 30s to 120s in `okx_config.json`.
- Added support for additional timeframes (1s, 5s, 10s, 15s, 30s) in the aggregation logic across multiple components.
- Updated `CandleProcessingConfig` and `RealTimeCandleProcessor` to handle new timeframes.
- Enhanced validation and parsing functions to include new second-based timeframes.
- Updated database schema to support new timeframes in `schema_clean.sql`.
- Improved documentation to reflect changes in multi-timeframe aggregation capabilities.
- 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.
