…l#353) Completes a rename decided in PR Universal-Commerce-Protocol#195 (get_product operation) but never executed on variant.json. The get_product operation introduced three distinct concepts that were previously conflated: request.selected — what the user chose (input parameter) product.selected — what the server resolved (response, post-relaxation) variant.options — what the variant IS (intrinsic, immutable) A variant's option values (Color: Blue, Size: Large) are intrinsic identity — they don't change based on user selections or server relaxation. The old name "selected_options" implied a relationship to user selection state that doesn't exist at the variant level. Schema: variant.selected_options → variant.options Docs: update variant examples in mcp.md and rest.md
