Resolves a specific product or variant by id, with full price, availability, and attributes.
Lookup makes product references stable: an agent that found an item yesterday can re-resolve it today with live price and stock before checkout.
We check the manifest for a catalog.lookup declaration alongside search, and that both resolve on the same transport.
