AnimateDread b2784b5a4d Enhance Feature and Topology Interfaces with Bulk Operations and Cache Management
- Added bulk read/write methods for feature caches in IFeaturesView and its implementations to optimize performance.
- Introduced LabelCacheInvalidateAll method to manage label cache invalidation alongside feature cache.
- Implemented PooledIndependentBars method in topology interfaces to account for additional independent observations.
- Enhanced risk budget management with throttling for peak-equity updates to reduce unnecessary file operations.
- Improved error handling and logging for ATR trailing stops to ensure better visibility of issues.
- Updated alt-data handling to prevent unnecessary operations during testing and optimization phases.
