automaticDiscountNode Deprecated, domain filter added, Shipping config updated

The "automaticDiscountNode" query has been marked deprecated; developers should switch to the "discountNode" query for retrieving automatic discount nodes. The "storefrontCrawlerSignatures" query now accepts an optional "domain" argument that filters signatures by their associated host. Two new market‑region types, "MarketRegionSubdivision" and "MarketRegionSubdivisionCountry", have been added to represent country subdivisions. ShippingConfiguration was altered: the "id" field and the former "activeOptionDefinitionsCount" field were removed, while "optionDefinitionsCount" now accepts a boolean "active" argument and is no longer deprecated. Inventory transfer error enums (InventoryTransferCreateAsReadyToShipUserErrorCode, InventoryTransferCreateUserErrorCode, InventoryTransferEditUserErrorCode) were expanded to include an "INVALID_TAG" value. Developers should update their queries and error handling to accommodate these changes.
