<#
.SYNOPSIS
Regenerates pkg\Assets\*.png from src\VRio.App\vwe.ico and rebuilds
resources.pri — run after changing the icon artwork.

The shell resolves the manifest's Square44x44Logo through the package
resource index; without resources.pri every icon lookup fails and the
Start menu / taskbar show a generic icon. After regenerating, bump the
Version in AppxManifest.xml (the shell's MrtCache is keyed by package
full name and serves stale lookups otherwise) and re-register with
Register-vRIO.ps1.

.PARAMETER MakePri
Path to makepri.exe. Auto-detected from the Windows SDK if installed;
otherwise extract it from the Microsoft.Windows.SDK.BuildTools NuGet
package (it is a zip: bin\<ver>\x64\makepri.exe).
