/**************************
 * Standardized Cache Hashing Utilities
 *
 * Provides consistent hashing for cache keys across the codebase.
 * All cache keys should use these utilities to ensure:
 * - Consistent format with type prefixes
 * - Collision resistance between different cache types
 * - Easy debugging and key parsing
 *
 * Key format: `{type}:{hash}` or `{type}:{version}:{hash}`
 *
 * @module cache/hash
