A pure Dart cache library with multi-layer storage, stale-while-revalidate, tag-based invalidation, and swappable storage adapters. Zero Flutter dependencies.

0.1.0

• Initial release.
• Typed multi-layer cache (L1 memory + optional L2 adapter) with automatic L2→L1 promotion.
• Stale-while-revalidate: returns stale value immediately while refreshing in background.
• Tag-based invalidation: invalidate groups of entries with a single invalidateTag() call.
• Three built-in eviction strategies: LRU, LFU, FIFO.
• Abstract CacheStore<K, V> interface for custom storage backends (Hive, SharedPreferences, etc.).
• CacheStats with hit rate, miss rate, eviction count and revalidation count.
• Pure Dart — no Flutter dependency, works in Flutter apps, Dart server and CLI.
