Module backend 

Storage backends for the cache layer.

The cache layer requires a CacheBackend implementation to persist cached responses. This module ships with:

• memory::InMemoryBackend — a fast, process-local cache backed by moka.
• redis::RedisBackend (optional) — a distributed cache when the redis-backend crate feature is enabled.
• memcached::MemcachedBackend (optional) — a distributed cache when the memcached-backend crate feature is enabled.

Backends are responsible for answering cache lookups, storing entries, and enforcing per-entry stale windows.
