      InformationalVersion: the content-identity stamp (SemVer +build metadata).
      Composed from SAMVersion + SAMSourceRevision when CI sets the latter. If CI already
      set InformationalVersion directly (e.g. SAM_Deploy installer.yml does this), respect
      that and don't overwrite. Local dev builds leave both empty -> no SHA attribute emitted.

      Suppress the SDK's SourceLink auto-append behaviour. By default, when SourceLink is
      configured on a project (via NuGet or repo settings), the SDK appends the project's
      OWN commit SHA to InformationalVersion (e.g. '2026.2.164.0+998af06.dd02a4c2...').
      We set InformationalVersion explicitly to SAM_Deploy's SHA (which encodes all 22
      submodule pointers), so the SDK's extra append is noise. False = keep our value clean.

    Projects where SDK assembly-attribute generation is disabled (legacy AssemblyInfo.cs
    with GenerateAssemblyInfo=false) OR projects where the SDK doesn't auto-generate
    attributes at all (classic-style csprojs that don't set the property — '' evaluates
    as not 'true') ignore the AssemblyVersion/FileVersion MSBuild properties above.
    Inject the attributes via a generated source file so those assemblies also get
    stamped by CI.
