Register a Book with Google Analytics (MkDocs Material)

This skill registers a new MkDocs Material site as a Google Analytics 4 (GA4) property, captures the Measurement ID, writes it into mkdocs.yml, verifies the tag is injected, and commits/deploys.

Inputs to gather first

Read these from the repo and/or confirm with the user:

• Repo path – local folder containing mkdocs.yml (e.g. ~/Documents/ws/<book>).
• Site URL – usually site_url: in mkdocs.yml (e.g. https://dmccreary.github.io/<book>/).
• GA settings (defaults below, override if the user says otherwise):
  • Reporting time zone: US / Chicago (GMT-05:00 Chicago Time)
  • Business size: Small – 1 to 10 employees
  • Industry category: Jobs & Education (GA4 has no literal "Education and Training" option; "Jobs & Education" is the correct closest match — use it unless told otherwise)
  • Business objective: Understand web and/or app traffic (best fit for a docs site)
