// Part 1A — completions gain a review workflow (submitted/approved/rejected)
// and a response_text field for the new submit_text requirement type.
// `status` is added as STRING + an explicit CHECK constraint, matching the
// pattern task_progress.type already uses on this CockroachDB instance
// (createTable auto-generates `check_type`; addColumn does not, so we add it
// ourselves) rather than the ENUM-with-no-constraint gap task_requirements.type
// happens to have today.
