PSR-14 events 

The PSR-14 event BeforeVerifyRequestEvent has been added in order to manipulate the additional request options that are sent to the Site-Verify-URL

The CaptchaConfigurationEvent has been introduced to make the default CAPTCHA provider configuration extensible, allowing listeners to adjust or extend provider-specific settings (e.g. endpoints, parameter names, request methods) before they are applied.

The ExpectedResponseEvent has been introduced to map provider-specific response formats to a unified boolean outcome, ensuring consistent validation handling across different CAPTCHA methods.
