Dynamic Memory-Efficient Memoization Cache with Expiration

performance caching memory-management functional-programming
Prompt
Design a high-performance memoization utility for Node.js that automatically manages memory by implementing a least-recently-used (LRU) cache with configurable time-based expiration. The utility should support async functions, handle promise resolution, and provide methods for manual cache invalidation. Implement type-safe generics and include performance tracking for cache hit/miss rates. Ensure the solution can handle complex function signatures and supports both synchronous and asynchronous caching strategies.
