Uniq Factory purchase

ultra.purchaseItem() has been removed

Earlier versions of the Ultra Wallet exposed ultra.purchaseItem(itemType, itemId), which opened Ultra's hosted checkout. The current wallet no longer depends on the Ultra platform backend, so that checkout was removed, and @ultraos/wallet-sdk 0.6.0 removed the method. Calling window.ultra.purchaseItem() now rejects with -32601 (method does not exist).

To sell Uniqs from a Uniq Factory, have the buyer sign the NFT contract's on-chain purchase.a action. See Ultra Wallet SDK → Selling Uniqs for a complete example.
