timelessnesses/game-of-life ? reverse-engineered prompt

Build me a simple Conway’s Game of Life app in Rust that opens a window and runs the simulation with SDL2.

I want it to feel clean and minimal, like a small hobby project, with the grid updating smoothly and the usual Life rules working correctly. It should be easy to start, easy to build, and keep the code compact and nicely formatted. If you need to check anything about the current SDL2 setup or build steps, look up the current docs online and use the standard Rust way to get it working.

Please make sure it compiles as a release build and includes whatever is needed so I can run it without fighting the setup too much.
