Pull Request Overview

This PR refactors the PerLevelDataLoaderDispatchStrategy to simplify level tracking and improve performance by replacing synchronized blocks with lock-free compare-and-swap (CAS) operations. The refactoring reduces the complexity of tracking mechanisms and introduces atomic operations for thread safety.

• Simplified per-level tracking by consolidating multiple tracking maps into a single state object
• Replaced synchronized blocks with CAS-based atomic operations for better performance
• Restructured subscription execution flow with separate callback methods
