Visible Barriers

Calls something that is on Kiln's roadmap. Parts of it may already run.

Evidence

Ran on Kiln's test stand (2026-11-04): VisibleBarriersCommon did not start: java.lang.NoSuchFieldError: Class net.minecraft.world.level.block.Blocks does not have member field 'net.minecraft.world.level.block.Block MOVING_PISTON'; VisibleBarriers did not start: java.lang.NoClassDefFoundError: net/fabricmc/fabric/api/client/rendering/v1/RenderStateDataKey.
