Add crash handler, game debug capture, timestamped logging, and logs/ directory

Browse Source 
- Add vectored exception handler (CrashHandler) installed from DllMain to
  reliably catch crashes before game CRT/SEH can override it, with x64
  stack walking via RtlVirtualUnwind and re-entrancy protection
- Hook OutputDebugStringA to capture game debug output into game_debug.log
- Move all log files into a logs/ subdirectory (legacyforge.log,
  game_debug.log, crash.log)
- Add millisecond-precision timestamps to all log entries
- Replace all raw printf calls with LogUtil::Log across every source file
  for consistent timestamped, file-persisted logging
