gmp-cli puts Google Marketing Platform in terminal

This is the rare AI-adjacent launch that feels genuinely useful, not just AI-flavored. The latest release adds agent-skill files for all four APIs, so the terminal-first pitch now has real discovery plumbing behind it.

• –One CLI across GA4, Search Console, Ads, and GTM cuts dashboard hopping for growth and analytics teams.
• –JSON/table/CSV output makes the tool usable by humans, scripts, and agent workflows without extra conversion glue.
• –The Google auth/setup burden keeps it squarely in power-user territory, especially for Ads where a developer token is required.
• –Apache 2.0 lowers the friction for forks, internal wrappers, or custom commands.
