/**
 * pop task assign — assign a task to an address/username (v6 takeover aware).
 *
 * Same claimability gate as pop task claim: an UNCLAIMED task assigns
 * normally; a CLAIMED task assigns only when the previous claim's deadline
 * has strictly passed (expired-claim takeover, TaskClaimExpired is emitted);
 * anything else fails fast before the transaction.
