Changes

I recommend you compare and contrast mine with the example template. Here's a high-level overview:

1. Removed the fallback paq-nvim package manager when not on Nix. I will never NOT be on Nix and I don't want to maintain a separate plugin list.
2. Keep a minimal categories to simplify the setup, i.e., I don't need to toggle on and off and risk wondering why the new plugin is not working (it's not enabled).
3. Get rid of for_cat handler for this fine control I don't need
4. I absolutely did not touch nixCatsUtils
