    Interface CacheAdapter<T>

    Cache adapter interface for pluggable storage backends.

    All methods are async to support Redis, IndexedDB, and other async backends. Adapters handle their own LRU eviction and cleanup logic.

    interface CacheAdapter<T> {
        size: number;
        clear(): Promise<void>;
        delete(key: string): Promise<boolean>;
        get(key: string): Promise<CacheItem<T> | null>;
        has(key: string): Promise<boolean>;
        set(key: string, item: CacheItem<T>, expiresAt?: number): Promise<void>;
    }
