ph cache

Generic caching infrastructure and a precompiled regular expression cache.

Highlights:

• ICache<K,V> / IMutableCache<K,V> - cache interfaces
• Cache / MappedCache - simple cache implementations, optionally with a Duration-based time-to-live (since 12.3.0)
• CacheEntry<V> - internal value+expiration holder used by MappedCache (since 12.3.0)
• CacheBuilder / ProviderCacheBuilder / ManualCacheBuilder - dedicated builders sharing the common base CacheBuilderBase with expireAfterWrite(Duration) and evictionInterval(Duration) to configure time-based expiration and opt-in background eviction (since 12.3.0)
• IMutableCacheWithExpiration.putInCache(K, V, Duration) / putInCache(K, V, LocalDateTime) - per-entry expiration overrides for the cache-wide TTL (since 12.3.0)
• CacheEvictionScheduler - process-wide singleton driving periodic evictExpired() calls for registered caches on one shared daemon thread (since 12.3.0)
• AnnotationUsageCache - cache for annotation presence checks
• RegExCache / RegExPattern / RegExHelper - compiled regex pattern caching and utilities
