/*!
 * System Methods Module
 * 
 * Extracted from box_methods.rs
 * Contains system-level Box method implementations:
 * - TimeBox methods (now, fromTimestamp, parse, sleep, format)
 * - DateTimeBox methods (year, month, day, hour, minute, second, timestamp, toISOString, format, addDays, addHours)
 * - TimerBox methods (elapsed, reset)
 * - DebugBox methods (startTracking, stopTracking, trackBox, dumpAll, saveToFile, watch, etc.)
