.SYNOPSIS
    End-to-end installer build: publish service + GUI, then run Inno Setup
    to produce dist/WebhookServer-Setup-{version}.exe.

.DESCRIPTION
    Reads the version from Directory.Build.props. Requires Inno Setup 6 (ISCC.exe)
    on PATH or in the standard install location. CI runs this same script after
    setup-dotnet + winget install Inno Setup.
