 * @description A lightweight TypeScript logger providing level-based filtering and tagging capabilities.
 * missionlog is designed as a drop-in replacement for console.log with additional features for
 * categorizing and filtering logs by severity levels and custom tags.
 *
 * Key features:
 * - Type safety with LogMessage and LogConfig interfaces
 * - Performance optimizations with level caching
 * - Enhanced API with structured logging support via EnhancedLogCallback
 * - Fully chainable API with all methods returning the logger instance
 * - Level checking with isLevelEnabled() and configuration reset()
 * - Full backward compatibility with existing logging patterns
