  .SYNOPSIS
  Runs GeneratePGOProfiles.ps1 with an audio-endpoint pre-check, retrying a few
  times.

  .DESCRIPTION
  On CI the virtual-cable audio endpoints (VB-Cable / VAC) intermittently fail to
  be enumerable when FreeDV starts a UT -- sometimes not yet up when the job
  begins, sometimes briefly dropping out mid-run right after SoX releases the
  capture device. Either way FreeDV aborts with a fatal "device cannot be found"
  message box.

  This wrapper waits for the required endpoints (ci/Wait-AudioDevices.ps1, which
  also restarts the audio stack), runs GeneratePGOProfiles.ps1, and retries the
  whole thing a few times before giving up. Must be run from the folder
  containing freedv.exe / GeneratePGOProfiles.ps1.

  .PARAMETER Attempts
  How many times to try the full collection. Default 3.
