patch

Lease recovery is now central-claim-aware: MeshLeaseManager.recoverAbandonedLease releases the central claim before clearing local task-row lease fields, and reconciles split-brain state via reconcileLeaseRow on the next scheduler / self-healing tick. Owner-offline handoff policy and progress-preserving handoff semantics are unchanged. Single-node deployments (no central claim store) keep the existing local-only behavior.
