<#
    launch.ps1  -  Starts the Automatic Thresholding GUI application.

    Outputs ONLY the numeric process id (PID) as the first line of stdout so
    the test harness can capture and manage the process. Works standalone
    (does not require build.ps1 to have been run in the same session), as long
    as the executable exists at the path below.
