Deploy a cookbook

This is the procedure every cookbook shares. Each cookbook's own SKILL.md carries what makes it different: the outcome, the questions, the acceptance test, the bill. It does not restate anything below, so read this once and then read the cookbook.

What a cookbook is

A folder of define* CDK resources that combine into one outcome, sitting on a shared base-gtm foundation so two cookbooks stack instead of colliding. Installing one is four moves: scaffold, fit, deploy, verify. The middle move is the one that matters, and it is the reason this is a skill and not a git clone.
