Function clear_property_store_dirty 

pub fn clear_property_store_dirty(store: Option<ResMut<'_, PropertyStore>>)

End-of-tick system that clears the PropertyStore dirty queue. Runs in crate::tick::TickStage::A11ySync after every consumer that peeks the queue (theme propagation, derivations, render-world frame dirty roll-up).

Without this the queue grows monotonically and dirty_global_names returns stale entries on subsequent ticks. The system is the wave-D replacement for clear_signal_dirty - same role, different backing store.
