This PR implements RP-initiated logout functionality following the OpenID Connect specification. It changes the logout flow from redirecting to the auth endpoint with request_credentials=required to using a dedicated logout endpoint.

Changes:

• Added logout configuration field and prepareLogoutRequest method to AuthRequestBuilder
• Updated the logout() method to use RP-initiated logout instead of forcing re-authentication
• Updated tests to reflect the new logout behavior
