Google Ads API — OAuth, REST Client & Keyword Research
Complete Google Ads API integration with zero gems — org-level OAuth connect flow storing only a refresh token, a plain Net::HTTP REST client (the official gem sunsets too fast to bake), GAQL reporting, Keyword Planner research (ideas + historical volumes), the no-API CSV fallback, and a template for saving the working setup as a local agent skill.
