/**
 * ByteEnum - Memory-Efficient Enum Utilities for TypeScript
 *
 * A high-performance, memory-optimized enum implementation with
 * type safety and runtime utility methods.
 *
 * Features:
 * - Minimal memory footprint using byte values or single characters
 * - High-performance lookups using Map-based implementation
 * - Type safety with TypeScript
 * - Runtime utility methods for validation and display
 * - Case-insensitive key handling (all keys normalized to UPPERCASE)
