StoreKit 2 In-App Purchases and Subscriptions

Build, review, and debug digital-goods purchases with modern StoreKit. Preserve the project's deployment target and existing StoreKit abstraction. Use original SKProduct/SKPaymentQueue APIs only when legacy support or an existing migration boundary requires them.

Route physical goods and real-world services to passkit; full submission/privacy/rejection audits to app-store-review; metadata and conversion work to app-store-optimization.
