.SYNOPSIS
    Loads release version from an SDK-style .csproj into shared context.

.DESCRIPTION
    Dedicated version-loading plugin. Reads <Version> from the first configured
    projectFiles .csproj, or from the nearest Directory.Build.props when the
    csproj omits it. Accepts SemVer prerelease (0.1.0-alpha.1 / beta / rc). Writes
    version plus the resolved projectFiles (csproj paths for later pack/publish)
    to the shared runtime context. Declares providesVersion = $true so the engine
    can discover it as the single release version source.
