Crust

I was always using Zsh, the I found Fish, and thinking of that mess, I have decided to make my own shell.

I decided that instead of using > or $, I am gonna go with +, which is the most unique part of the project.

I added an AI integration and custom ls commands, which I think are the coolest features.

This is still a work in progress. Definitely do NOT set crust as your login shell. For now, it relies on your current shell.
