# Console-window watcher for the ELEVATED job path (app/igneum-app/src/jobrun.rs run_script with elevated=true: the
# app's headless powershell runs `Start-Process powershell.exe -Verb RunAs -Wait -WindowStyle Hidden`, the AppInfo
# service creates this process after the UAC prompt). The engine's power cap, the sweep helper and the clock sync take
# the same road with cmd.exe (platform.rs run_elevated, sync_clock; app/windows/host.cpp runElevated). This script
# runs INSIDE the elevated process and reports whether its own console has a window, which host serves it, and
# whether a Windows Terminal window appeared for it. One UAC prompt on the PC; a few seconds.
