Contract
- LRUCache get and set operations retrieve cached values and respect maximum capacity (max) by evicting the least recently used entries
- LRUCache maxAge configuration expires entries after duration while allowStale and prune manage stale item retrieval and cleanup
- LRUCache length calculation tracks weighted item sizes and triggers eviction when total length exceeds max capacity
