GitLab Duo Core moves to usage-based billing

Starting in GitLab 19.0, GitLab Duo Core moves to usage-based billing. Code Suggestions in the Web IDE and desktop IDEs now consume GitLab Credits.

GitLab Duo Chat is also changing. For GitLab Duo Core users, Chat is now agentic and runs on GitLab Duo Agent Platform. To use GitLab Duo Chat in the GitLab UI or desktop IDEs, enable GitLab Duo Agent Platform for your instance or top-level group.
