v4.5.3

Fixes

• Pulse mode sends the endpoint stop again (#129): the 4.4.0 "no endpoint stop for self-stopping motors" change was too broad — it lumped Pulse mode in with Toggle, but the two are not the same. Toggle's "stop" re-pulses the direction relay (which would restart the motor), so skipping it there is correct; Pulse mode has a dedicated stop relay (a stop switch is required), and its momentary controller latches the direction command and keeps running until it receives that stop pulse. With the stop skipped at 0%/100%, the controller was left stuck "moving" — the cover only responded after several clicks, the Stop was never delivered, and the physical wall/PLC buttons appeared blocked while the controller thought it was still running. Pulse mode now pulses its stop relay at the endpoints again (deferred by Endpoint run-on time if configured), exactly as it did in 4.3.0; because the stop is a separate relay, it can never restart the motor. The same applies to a separate tilt motor — its tilt-stop relay is pulsed at the tilt endpoints too. Toggle and wrapped-cover modes are unchanged.
