hexratcc/sigma — reverse-engineered prompt

Build me an early working version of Sigma, a small compiled language that feels like C but is statically typed and more data oriented, with a strong focus on speed and low level control. I want the current scope to stay realistic, so make it CPU first and treat GPU kernels as future facing groundwork, not a finished feature.

The main thing I want is a command line compiler that can take a simple .s source file and compile it, like sigma compile main.s, with enough basic language support to show the direction of the project. Please wire up the build so it works cleanly on Windows and Linux, generate project files with Premake, and make sure the tests run. If parts are unfinished, leave clear placeholders and notes instead of pretending they are done.

Keep the codebase organized enough that someone could keep developing the language later. If you need details that are missing here, look up the current docs and repo context online.
