Walkthrough

The change updates version numbers in the Appwrite PHP SDK client. The user-agent header string and x-sdk-version header are both incremented from version 20.2.0 to 20.2.1. These are default global headers defined in src/Appwrite/Client.php. No functional logic, control flow, or public API signatures are modified.
