Module dedup_cache 

LRU cache for deduplication hash lookups.

This module provides a fixed-capacity Least Recently Used (LRU) cache that accelerates repeated hash lookups during deduplication scans. When the cache is full, the least recently accessed entry is evicted.

Key Types

• LruCache - Generic fixed-capacity LRU cache
• HashCache - Specialised cache mapping file paths to hash digests
• CacheStats - Hit/miss statistics for the cache
• DedupSessionCache - Session cache for thumbnails and fingerprints
