Detailed Description

Single hash entry in the in-memory cache.

This structure is managed by uthash and represents one key/value association tracked by the cache. Keys are native 64-bit integers, hashed directly by uthash without string conversion. Callers do not allocate or free individual entries directly; use the cache API helpers.

Lifetime & ownership:

value is an opaque pointer supplied by caller; the cache does not take ownership unless a free_func is registered on the CacheHeader.
