Module cache 

LRU cache for signature verification results.

Avoids re-verifying identical (algorithm, public_key, message, signature) tuples. Thread-safe via Mutex. LRU eviction by entry count.

Usage

use confium_composite::cache::VerificationCache;

let cache = VerificationCache::new(1024);
// First call: miss → verify → cache result
// Second call: hit → return cached result
