Approved. This PR cleanly replaces the Unix-only shell script with a cross-platform Python script, improving Windows compatibility without changing core behaviour. The implementation is clear and well-structured.
Non-blocking: build paths are hardcoded to Debug/net8.0 and _framework assumes dotnet build these can be revisited if build targets change.
