CLI provides a prerequisites check/message between install=>project creation stages

[lasomethingsomething]

User story

As a dev, I want the CLI to check my prerequisites (Docker, PHP, Composer, Node, DB, ports, permissions) and tell me what's ready, missing, or optional, so that I can fix gaps before creating a project.

Can add checks to overcome "I'm setting my project, and my colleague set this up for me, and they did it in a way that misses some steps or isn't recommended."

Instance where doctor is useful, to bridge communication and collaboration gaps between dev-users. Shared logic with project create.
