mcneel/rhino-developer-samples ? reverse-engineered prompt

Build me a clean sample code repository for Rhino and Grasshopper developers, organized by language and SDK like the Rhino developer samples site.

I want the project to include separate sample folders for things like C plus plus, Grasshopper, openNURBS, RhinoCommon, rhino3dm, Compute, Rhino.Inside, RhinoMobile, RhinoPython, RhinoScript, and Zoo, with each sample kept simple and easy to run or copy into a real project.

Please make the structure clear, add basic README files where helpful, and include a few realistic starter examples that show how to work with Rhino and Grasshopper in the supported languages. If anything depends on current Rhino docs or SDK details, look up the latest info online and use that. The goal is to give developers practical reference code they can browse by topic and language, with consistent naming and enough setup guidance that they can understand how to use each sample without having to guess.
