Other information

I made it so it checks you're in the root of the project, because although some commands can work throughout the project structure, some fail so we should encourage people to just run it from the root path

Sweeet! Two things:

1. Can you use the pkg-dir package that's already installed instead of find-package-json?
2. Could you add a detailed comment in the utils file describing the blitz app detection and all the possible outcomes?

Thank you so much!

This is beautiful — great work!!!

@Zeko369 i think we have commands that check for this manually, can you follow up and convert those usages to use the new utils?

[Zeko369]

@aem you pushed the new utils?

Ah sorry my comment was a bit unclear. Since this hook/util you added handles it for all commands, can you remove any checks for blitz.config in existing commands?
