server_cache 0.2.0

Framework-agnostic cache runtime for server ecosystems (portable, from server_data/cache).

0.2.0

• Replace map-based store configuration and string-driver resolution with concrete Store registration and typed StoreConfiguration factories.
• Made store-only-if-absent operations atomic across the file, Redis, array, and null stores.
• Corrected file-store TTL handling and namespaced tagged-cache keys to avoid cross-scope collisions.
• Made tag invalidation and file-lock operations consistently await their backing store writes.

0.1.0

• Initial extraction from server_data/src/cache (PR F)
