openRedeemOfferCode abstract method

Future<Purchase?> openRedeemOfferCode()

Open the platform's offer/promo code redemption flow. Resolves the redeemed purchase only when the store reports it synchronously; every other path resolves null, so reconcile through the purchase listeners. Throws when a redemption flow exists but cannot be opened. Available in OpenIAP Spec 3.3.0 / openiap-apple 3.3.0 / openiap-google 3.4.0. Replaces presentCodeRedemptionSheetIOS and openRedeemOfferCodeAndroid. See: https://openiap.dev/docs/apis/open-redeem-offer-code
