WorldEffectType: new VEGETATION_DIES variant. WorldEffectsModule: emits VEGETATION_DIES whenever soilQuality < 20 OR pollutionScore > 30, mirroring VegetationModule's bad-conditions gate so block changes stay in sync with the data-layer die-off. Intensity is the max of the soil-shortage and pollution-excess fractions. NeoForgeWorldEffectExecutor.killVegetation(): - Detects tree canopy by comparing MOTION_BLOCKING (includes leaves/logs) height vs MOTION_BLOCKING_NO_LEAVES (ground) height. - When canopy is present: strips all leaf blocks downward from the canopy top; at intensity > 0.3 also removes upper trunk log sections, leaving bottom two blocks as a visible stump. - When no canopy: clears surface plants (short grass, fern, tall grass, large fern, saplings, dandelion, poppy). Previously the simulation correctly tracked vegetation pressure dropping to zero but the Minecraft world remained a full forest, so there was no visible feedback for degradation. /lw demo degrade now visibly kills the forest canopy while the succession stage regresses.
