Enhance Argo CD integration by adding support for a bootstrap root application. Update group_vars/all.yml and role defaults to include noble_argocd_apply_bootstrap_root_application. Modify tasks to apply the bootstrap application conditionally. Revise documentation to clarify the GitOps workflow and the relationship between the core platform and optional applications. Remove outdated references and streamline the README for better user guidance.
