codecrafters-io/build-your-own-redis ? reverse-engineered prompt

I want you to build out this Build Your Own Redis coding challenge so it feels complete and ready for learners.

Make the challenge flow clearly from the first simple step to a working Redis like server, with sensible starter files, stage descriptions, and a clean final solution path. Keep the instructions easy to follow for someone who is learning by doing, and make sure each stage builds on the last one in a natural way.

Use the existing course setup here as the base, and if you need to, look up the current docs for the course tools online. I want the whole thing to feel polished, consistent, and runnable without a lot of manual fixing.
