Integrate Kotlin Multiplatform without manual iOS linking

The Kotlin Multiplatform SDK v3.0.0 eliminates the need to manually link the native iOS framework when integrating RevenueCat into KMP projects. The SDK now handles the iOS dependencies internally.

You no longer need to add PurchasesHybridCommon or PurchasesHybridCommonUI as separate native iOS dependencies via Swift Package Manager or CocoaPods. The SDK now handles this internally when you add the purchases-kmp dependency to your Gradle build file.

This removes the most complex step of KMP setup, making integration as simple as adding a single Gradle dependency. If you maintain cross-platform apps, this cuts down the manual configuration work required to get your in-app purchases running.
