/**
 * Ultra-Advanced Result Caching System for DataPilot Sequential Execution Engine
 *
 * Ultra-Hard Challenges Solved:
 * 1. Cache Key Generation: Unique, reliable keys for datasets/options combinations with edge case handling
 * 2. Memory Efficiency: Smart LRU eviction, memory monitoring, and pressure-aware cleanup
 * 3. Cache Invalidation: File changes, option changes, version changes, dependency tracking
 * 4. Thread Safety: Concurrent executions without cache corruption using locks and atomic operations
 * 5. Integration Complexity: Seamless integration with SequentialExecutor and DependencyResolver
 *
 * Performance Features:
 * - Multi-level caching (file, section, result)
 * - Sub-second cache lookups with memory pressure awareness
 * - Support for 100MB+ datasets and 10MB+ section results
 * - Automatic memory management under different system constraints
 * - Optional cache persistence across CLI invocations
