Final maintenance release before this SDK is retired in favour of
https://github.com/PaystackHQ/paystack-sdk-ios. CocoaPods trunk stops
accepting new podspecs on 2 Dec 2026, so no further versions ship after this.

Keeps existing merchants building and charging until they migrate:

• Require iOS 15.0+ / Xcode 26; stop treating warnings as errors
• Requery by access_code (5s × 12, then error), with a temporary fallback to trans for charges started without one
• Send Authorization and Paystack-Version on every request, fetchStates included
• Isolate concurrent chargeCard calls and reset optional callbacks per charge
• Fix crashes on missing transaction id and non-UTF-8 response bodies
• Example app runs without a backend; refresh README and GUIDE for the move

Public API is unchanged; deprecation attributes stay in place.
