product_geo_agent: AI agent for Shopify GEO and AEO

A Rails command-line AI agent that checks whether AI assistants can find and recommend a Shopify product, scores it 0 to 100 and names the top gaps (GEO and AEO).

An agent is a loop, not a single model call. This one has five tools (product data, FAQ page, FAQ metafield, structured data, AI citation check) and decides which to call. Three real audits on a sandbox store scored 70, 33 and 10 out of 100 (single runs); across five eval runs the complete product scored between 65 and 70.
