Merge eureka/aetheria-release-sim-speed: one SimClock steps the zone, presenters draw ahead by Lead

AetherDrive.cs: master deleted the behaviour (2cfdc728); the branch only added a
TurnRate line to it. Deletion kept. Thruster remains the one rotation actuator
and feeds Entity.TurnRate. No sim stepping outside the clock on master
(mines presenter, Pirates AI, lot-product all step through Zone.Update).
