random idea: add a "customize harness" button somewhere that forks & clones this repo, adds it as a project, and generates a worktree

In the spirit of making it as easy as possible to customize harness, what if we added a "customize harness" button that did all of the setup to get harness cloned & running locally and helped you add whatever feature you wanted?

One of the things I think is cool about harness (and generally the state of software engineering right now in general) is that people can pretty easily customize tools to be whatever they want them to be. It would be nice to support that as much as we can.

A stretch goal of this idea would be: Figure out how to support people running their own custom version of harness. Like once you have made your own customizations, it's kind of annoying to wait an entire release cycle for your features to be included
