 - Split VS Code Marketplace and Open VSX publishing into separate release jobs and added idempotent publish scripts so duplicate-version reruns succeed while real publish errors still fail.
 - Updated package/readme wording from `immutable-first` to `immutable-by-design` to reflect immutable-only semantics.
 - Switched NuGet package readme for `MagnusOpera.FScript.Language` and `MagnusOpera.FScript.Runtime` to a targeted `NUGET.md` with logo, overview, rationale, and license.
