.SYNOPSIS
    .NET publish plugin for producing application release artifacts.

.DESCRIPTION
    This plugin publishes configured .NET projects into the artifacts directory
    and appends those publish folders to shared archive inputs so later plugins
    can zip them next to any earlier pack outputs. Existing NuGet package facts
    (packageFile) are left unchanged.

    Optional runtimeIdentifiers (or runtimeIdentifier) produce per-RID folders
    under artifactsDir/<ProjectName>/<rid> for desktop installers (Windows MSI /
    Linux Flatpak). When RIDs are set, selfContained defaults to true.
