Usage:
  ai/tools/operator-questions/resolve-stale-approved-actions.sh [--dry-run] [--json]

Marks stale, non-executed approved-action intents as resolved_stale with audit
evidence. Executed, denied, ignored, and already-resolved records are left
untouched. This never executes actions and never deletes state.
