    launch.ps1 - Starts the Cuckoo Chess GUI desktop application.

    Launches the self-contained native app-image produced by build.ps1
    (jpackage bundles its own Java runtime, so no external JDK is required).

    Outputs ONLY the numeric PID as the first line on stdout.

# $out[0] index the first CHARACTER of the PID instead of the whole number.
