Assemble checkout-ready cart(s) in ONE call for a multi-product (and optionally multi-store) request. Creates a cart per store, adds all items, and sets the shipping address — then returns the cart(s) with delivery options to choose. Use this when the buyer lists several products at once (optionally across stores) and/or gives their address up front, instead of calling create_cart/add_to_cart/set_shipping_address separately. Does NOT select delivery, check out, or pay — the buyer picks delivery (select_shipping_option) and approves checkout/payment per store afterward. Out-of-stock items are reported; pass customer.email to auto-arm a back-in-stock alert for them.
