- Introduced a new handler 'docker compose pull' that runs only once per
{{ docker_compose.directories.instance }} directory by using a lock
file under /run/ansible/compose-pull.
- Ensures idempotency by marking the task as changed only when a pull
was actually executed.
- Restricted execution with 'when: MODE_UPDATE | bool'.
- Improves update workflow by avoiding redundant docker pulls during
the same Ansible run.
