fix(engine): stop coal_feeder before starting distributor on acc_time trigger 

When accumulated_run_sec reaches acc_time_sec, the coal feeder must be stopped
before entering DistributorRunning state. Previously the feeder was left running
while the distributor also ran, which is incorrect per the control spec.
