DayNightCycle now reads time_of_day from SimulationManager group node, falling back to self-tracked elapsed for lookdev scenes. Simulation starts at 06:00 morning (tick 50) by default. TimeDial reads directly from SimulationManager and displays HH:MM format with a 24-hour dial arc. Removed initial_cycle override from JajceLookdev.
