.SYNOPSIS
    Rebuilds the ClickOnce installer for BulkArchiveMailer.AddIn (Способ А
    in ../docs/BUILD.md) without hand-typing the long MSBuild -t:Publish
    command each time.

.DESCRIPTION
    Wraps:

        MSBuild.exe BulkArchiveMailer.AddIn\BulkArchiveMailer.AddIn.csproj -t:Publish -p:Configuration=Release
            -p:PublishUrl=<repo>\BulkArchiveMailer.AddIn\bin\Release\app.publish\
            -p:InstallUrl=<repo>\BulkArchiveMailer.AddIn\bin\Release\app.publish\
            -p:PublishDir=bin\Release\app.publish\ -p:UpdateEnabled=false

    MSBuild.exe is located via vswhere.exe first (works across VS
    installs/versions/editions); if vswhere itself isn't found, falls back
    to the fixed path this repo has been built with so far
    (D:\VS2022\MSBuild\Current\Bin\amd64\MSBuild.exe). Pass -MSBuildPath to
    override either lookup explicitly.

.PARAMETER MSBuildPath
    Explicit path to MSBuild.exe. Skips both the vswhere lookup and the
    hardcoded fallback when supplied.

.EXAMPLE
    .\deploy\publish-clickonce.ps1
