-Cache Manager V1 - Multi-level KV Cache Management System
-
-This module provides a three-level cache hierarchy:
-- Device (GPU) → Host (CPU) → Storage
-
-Key components:
-- KVCacheBase: Abstract base class defining common interface
-- CacheManager: Scheduler-side cache management with block pools
-- CacheController: Worker-side cache control for transfer operations
-- CacheTransferManager: Manages cache transfer operations
-- LayerDoneCounter: Tracks layer-by-layer transfer completion
-- create_storage_scheduler: Factory function to create StorageScheduler
-- create_storage_connector: Factory function to create StorageConnector
-- create_transfer_connector: Factory function to create TransferConnector
