/**
* Cache Invalidation - 88% token reduction through intelligent cache invalidation
*
* Features:
* - Multiple invalidation strategies (immediate, lazy, write-through, TTL, event-driven, dependency-cascade)
* - Dependency graph tracking with parent-child relationships
* - Pattern-based invalidation with wildcard support
* - Partial invalidation (field-level updates)
* - Scheduled invalidation with cron support
* - Invalidation audit trail
* - Smart re-validation (only validate if needed)
* - Batch invalidation with atomic guarantees
