I think we should remove the .envrc file and leave that up to the user. Also we shouldn't force install Alejandra since that's not part of the base project. The only hard requirements are node and pnpm. Anything outside of that should be up to the user

The .envrc file leaves it up to the user. You dont want to use it, dont run direnv allow.

Also I just added alejandra to format nix flakes in case people make more changes to it and adds stuff. I can remove it if needed.

Okay, we can leave the direnv stuff. We should probably also add .tool-versions for node and pnpm for ASDF and mise support. Also yeah definitely need to remove alejandra

[Uzaaft]

Fixed. R? @mehalter

[mehalter]

You need to remove alejandra

[mehalter]

I went ahead and fixed the rest of the alejandra removal and added a .tool-versions for more dev environment support.
