March 2026 monthly summary for the m1a2st/kafka repo. Focused on architectural refactors to improve testability, modularity, and API hygiene across the trogdor integration and internal utilities. Delivered two key features: 1) Scheduler Utility Relocation for Improved Testability, relocating the Scheduler, SystemScheduler, and MockScheduler from the clients module to trogdor to improve modularity and ensure client-side tests still function with a local MockScheduler. 2) Internal Utilities Reorganization, moving ImplicitLinkedHashCollection, ImplicitLinkedHashMultiCollection, and ByteUtils from the public API (common.utils) to an internal package (common.utils.internals) to clarify API boundaries and improve maintainability.
