fix cluster stubs: deterministic fallback, payload forwarding, and handler guards

- Replace non-deterministic map range fallback with sorted node selection in PlaceActor and RebalanceShards - Add Body field to MessagePayload to preserve message data during cross-node routing - Forward actual message body in route_message handler instead of discarding it - Add self-message guard to route_message handler to prevent loops - Add nil guard for shardMap in handleRebalanceRequest - Add self-message guard to handleRebalanceRequest in DistributedVM
