Merchant Listing: Valid Detection

This scenario tests a basic valid merchant listing with all required and recommended fields present, but no truly optional fields like reviews or aggregateRating.

Expected outcome:

• One valid Merchant listing item detected
• Zero errors, zero warnings
• Includes required fields: name, image, description, offers (non-aggregate)
• Includes recommended offer fields: price, availability, shippingDetails, hasMerchantReturnPolicy
• Excludes truly optional fields like itemCondition, reviews, aggregateRating
