v1.0.0

New endpoints & domain update

• New API base domain — switched from api.storekit.itunes.apple.com to api.storekit.apple.com (and sandbox equivalent).
• New endpoints added:
  • getAppTransactionInfo — fetch a customer's signed app transaction info
  • finishTransaction — notify the App Store that a transaction is processed
  • getRefundHistory — paginated list of a customer's refunded transactions
  • setAppAccountToken — set/update the app account token for a transaction
  • extendRenewalDatesForAllActiveSubscribers + getStatusOfSubscriptionRenewalDateExtensions — mass renewal-date extension and status lookup
• getTransactionHistory now always uses v2; removed the deprecated version/TransactionHistoryVersion parameter.
• sendConsumptionInformation upgraded to the v2 endpoint.
• New notification payload types — external purchase token and app-data payloads.
• New model types/enums

Dependencies & ESM-only build

• ESM-only output
• Dependency bumps — jose 5 → 6, TypeScript 4 → 6, Prettier 2 → 3, @types/node updated; removed ts-node.
• Node ≥22 required (engines); tsconfig retargeted to a Node 22 base (es2022/nodenext).
