/**
 * Retention sweep — `npm run sweep` (add `-- --dry-run` to look first).
 *
 * Deletes what /terms §9 says we delete: expired sessions, sessions over 90
 * days, expired verification tokens, and build artifacts over 30 days.
 *
 * The build worker runs this daily on its own (see build-worker.ts), so this
 * script exists for two other cases: checking what is about to go before it
 * goes, and cleaning up on a box where the worker is not running.
