First-time project setup

Input: $ARGUMENTS — the website to set up, and where its customers are. If that placeholder is empty or still literal, take the website from what the user asked; if they named none, ask for the domain — nothing else is required.

You are setting up the thing every other Ubersuggest workflow reads from. A project is what makes rankings, competitors and AI visibility trackable over time; without one, every other skill can only look at public data.
