OneshotGH/supremacy — reverse-engineered prompt

Build me a clean educational C++ project from this Supremacy CS:GO source so I can study how an old game mod style codebase is organized without making anything usable for cheating online.

I want it to open in Visual Studio, compile in Release x86, and run as a safe offline demo. Keep the commented learning style, but replace any real game hooking, injection, anti cheat bypass, or live CS:GO interaction with harmless mock data and stub functions. The demo should show the menu system, controls like checkboxes, sliders, dropdowns, color pickers, keybinds, config saving, and example visual settings using fake player or scene data.

Please clean up build errors, organize the code enough that a beginner can follow it, and add a short README explaining how to build it and what parts are mocked. Look up current Visual Studio docs online if you need to.
