/**
 * @fileoverview LRU Cache for compiled Minimatch patterns
 *
 * This module provides a simple LRU (Least Recently Used) cache for Minimatch
 * instances. Caching compiled patterns significantly improves performance
 * when the same pattern is used multiple times with the minimatch() function.
 *
 * The cache stores compiled Minimatch instances keyed by a combination of
 * the pattern string and relevant options that affect compilation.
