StoreProduct not exposed in public API of superwallkit_flutter

[OrcunJoyoLabs]

When implementing Superwall Delegate to log actions taken on paywalls, I noticed that the StoreProduct class is not properly exposed in the public API of superwallkit_flutter. This is causing issues when trying to access product information in delegate callbacks.

Current behavior

Currently, StoreProduct is only available by importing directly from the source directory:

import 'package:superwallkit_flutter/src/public/StoreProduct.dart'

Expected behavior

StoreProduct should be properly exported from the main package so it can be imported directly:

import 'package:superwallkit_flutter/superwallkit_flutter.dart'

Use case / Why this is needed

When implementing custom logging in delegate callbacks, we need access to the product information. For example:

case EventType.transactionComplete:
  final transaction = eventInfo.event.transaction;
  eventToLog = superwallTransactionComplete(
    paywallIdentifier: paywallIdentifier,
    productId: product?.productIdentifier,
    transactionId: transaction?.storeTransactionId,
  );

Having to import directly from the source directory (src/public) is not a sustainable solution as it relies on internal package structure that may change in future versions.

Hey @OrcunJoyoLabs !

Thanks for the report, seems we somehow missed this one - adding it to the next update.
