Work and attempts
Work is the request; attempts are the tries. How Excellent records each attempt against the repository state and agent setup, and links retries.
Work is the requested outcome. An attempt is one try to complete it.
excellent run --agent <role> --task <task-id>Expected result: Excellent creates an attempt record and binds it to the repository state and the agent setup.
