 * Convergent post-CFN orphan sweep (AC3.3). After CFN reports the stack gone,
 * any bucket captured pre-destroy that still exists AND still carries a
 * DESTROY-intent marker is emptied and deleted SDK-side, so re-running an
 * interrupted destroy converges instead of stranding marked buckets.
 *
 * Convergence is bounded by capture-before-destroy: the captured list dies
 * with the process, so a crash after CFN reports the stack gone but before
 * this sweep completes leaves survivors a re-run cannot see — the deleted
 * stack no longer lists its resources, and the re-run captures nothing.
 *
 * The tag re-probe is the name-reuse guard: a bucket recreated by another
 * owner after CFN deleted the original classifies "retained" and is never
 * touched. Already-gone buckets are convergence, not failures. The sweep
 * never fails the destroy — per-bucket problems warn and continue.
