Description

> items are not pro-actively pruned out as they age

I'm thinking about memory leaks in this case if LRU is used on a server and cache key is something time based (e.g "today"). In this scenario old keys (when today has moved to the next day) will never be accessed (neither `set` or `get`), so never pruned. How would you solve it?

I see one simple/stupid solution to do like `setInterval` that does `cache.clear()` once in a while. But that would clear all items, not only stale.

Research direction

Start by reading the cache implementation and its existing tests to understand how entries are stored, accessed, and evicted. Define how age-based pruning should work for keys that are never accessed, including its scheduling and resource costs. Done means stale entries are removed without clearing live entries and the behavior is covered by tests.
