Feature Request: Apple Retention Messaging API Support

Hi Adapty team,

I'm an Adapty customer and wanted to formally request support for Apple's Retention Messaging API.

This API lets apps show personalized cancellation offers directly in iOS Settings when a user taps Cancel. It's a significant churn-reduction tool and RevenueCat has already shipped a managed integration for it. I'd like to stay on Adapty, but the lack of this feature may push me to reconsider.

Building and maintaining the required backend myself (real-time endpoint, promo offer signing, per-locale message config) is exactly the kind of infrastructure I rely on Adapty to handle.

Please consider adding this to your roadmap. Happy to be a beta tester.

Thanks!
