/**
 * Recover a command whose lease expired or whose absolute deadline passed.
 *
 * A claimed command returns to `accepted` at its original FIFO position while
 * attempts remain, and is dead-lettered once they are gone. A
 * cancellation-requested command becomes `cancelled` with `cleanupPending:
 * true` — the mailbox stopped waiting for the claimant, which is not the same
 * as the claimant having stopped. Any non-terminal command past its absolute
 * deadline is dead-lettered regardless of remaining attempts.
