.SYNOPSIS
    #422 rate measurement: N offline captures WITHOUT a debugger (the debug
    heap can change allocation layout and mask a corruption), optionally
    forcing a non-incremental Release rebuild of AcDream.App before run 1 so
    run 1 is a genuine "first launch after a build" — the condition under
    which the VM7 matrix reproduced the exit.
.EXAMPLE
    pwsh tools/i422/loop-plain.ps1 -Runs 12 -Preset retail -Resolution 1920x1080 -WarmupMs 45000 -RebuildFirst
