Codewalk as replacement #1

Hi, codewalk was heavily inspired by OpenMode, which was a great source of inspiration. Since it’s based on OpenMode, I’ve added a clear disclaimer at the bottom of the README.

I started codewalk to share my perspective, but noticing that OpenMode hasn’t received updates in recent months, I’d like to submit a PR suggesting codewalk as an updated alternative.

This is just a suggestion, and I gain nothing beyond what I’ve already done by creating codewalk. Thanks again for the inspiration.
