REM Tests DDNS task functionality on Windows systems
REM Exits with non-zero status on verification failure
REM Usage: test-task-windows.bat [DDNS_COMMAND]
REM Examples:
REM   test-task-windows.bat                    (uses default: python3 -m ddns)
REM   test-task-windows.bat ddns               (uses ddns command)
REM   test-task-windows.bat ./dist/ddns.exe    (uses binary executable)
REM   test-task-windows.bat "python -m ddns"   (uses custom python command)
