#Requires -Version 5.1
<#
.SYNOPSIS
  Builds a Libation Windows setup.exe from a published bin directory using Inno Setup.

.DESCRIPTION
  Optionally runs dotnet publish (same projects as CI), removes standalone WindowsConfigApp
  artifacts, then compiles Scripts/Windows/Libation.iss.

.PARAMETER Version
  Libation version string (e.g. 13.4.1).

.PARAMETER Ui
  Avalonia (Chardonnay) or WinForms (Classic). Classic is x64 only.

.PARAMETER Architecture
  x64 or arm64 (Avalonia only).

.PARAMETER BinDir
  Folder containing published files. Defaults to repo-root bin.

.PARAMETER SkipPublish
  Skip dotnet publish; BinDir must already contain a complete publish output.

.EXAMPLE
  .\Build-WindowsInstaller.ps1 -Version 13.4.1 -Ui Avalonia -Architecture x64

.EXAMPLE
  .\Build-WindowsInstaller.ps1 -Version 13.4.1 -Ui WinForms
