Add basic AutoCAD command test scripts
Introduce a set of C# scripts for AutoCAD that implement basic drawing and editing commands, including creating lines, circles, arcs, polylines, copying, moving, and scaling selections, as well as simple layer management and block listing. These scripts are intended for testing and demonstration purposes.
