Implement Regime Reversion Strategy and remove regime_detection.py
- Introduced `RegimeReversionStrategy` for ML-based regime detection and mean reversion trading. - Added feature engineering and model training logic within the new strategy. - Removed the deprecated `regime_detection.py` file to streamline the codebase. - Updated the strategy factory to include the new regime strategy configuration.
