Sparse package icons need resources.pri at the external location

The shell resolves Square44x44Logo through the package resource index;
this package never had a resources.pri, so every icon lookup failed and
Start/taskbar showed a generic icon regardless of the Assets PNGs.
Empirically (SHLoadIndirectString against the live package), with
AllowExternalContent MRT loads resources from the EXTERNAL location,
not the manifest's folder — so Register-vRIO.ps1 now copies Assets\ and
resources.pri next to the exe before registering. Make-Assets.ps1
regenerates the PNGs from vwe.ico and rebuilds the pri (needs makepri
from the Windows SDK / SDK.BuildTools NuGet). Package version bumped;
the MrtCache is keyed by package full name, so same-version
re-registration serves stale lookups.

+.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

+otherwise extract it from the Microsoft.Windows.SDK.BuildTools NuGet
+package (it is a zip: bin\<ver>\x64\makepri.exe).
