Subject: [PATCH] feat: suppress console window for tunnel helper commands on
 Windows

Add CREATE_NO_WINDOW flag to all tunnel helper Command invocations on Windows to prevent console window flashing during connect, disconnect, and metrics operations. Import CommandExt trait and define CREATE_NO_WINDOW constant for Windows builds.
