📝 Walkthrough

Walkthrough

This PR releases version 0.0.9 with documentation of the plugin's hybrid SumUp SDK integration. The release notes describe the PHP-version-dependent approach using the official prefixed SDK on PHP 8.2+ with WordPress HTTP fallback for earlier versions, removal of an unused dependency, transport abstraction with SDK-to-HTTP fallback, response normalization, runtime guards, and regression test coverage. Plugin version metadata is updated from 0.0.8 to 0.0.9 in both the header and version constant.
