Refactor Argo CD application management by removing noble-kyverno and noble-platform configurations, transitioning to Ansible-driven installations. Update documentation to clarify the optional nature of app-of-apps and the role of kustomization.yaml as an empty resource holder. Ensure users are informed about the need to delete stale Applications when migrating from previous configurations.
