.SYNOPSIS
  Pack Navis.exe into an MSIX for Microsoft Store / sideload.

.DESCRIPTION
  Builds Store assets, stages AppxManifest + Navis.exe, runs MakeAppx.
  Prefers MSIX over PWA: Navis needs Win32/WebView2 VPN and system-proxy access.

.EXAMPLE
  .\scripts\pack-msix.ps1
  .\scripts\pack-msix.ps1 -Version 3.9.0.1 -Publisher "CN=EvilFox"
