Zcraft Decoration

Updates:
DirectionUtil: shared horizontal index (no more duplication between block and cache). ModelJsonResolver: resolution of JSON model strings. PersistentShapeStore: gzip disk cache extracted from ModelShapeCache. ShapeCacheWarmup: centralized asynchronous warmup (single entry point). block_list.txt: replaces test_block_list.txt (test file removed). Loot: getDrops uses super.getDrops(); JSON loot tables are once again included in the JAR (Gradle exclude removed). VoxelShape Mixin: clip acceleration only if the shape has ≥ 32 boxes; forAllEdges optimized only with the profiler (-Dzcraft_decorations.shapeProfiler=true). Proxy cleanup: radius based on model bounds, not a fixed radius of 4. CollisionProxyBlock: removed redundant removeBlockEntity in onRemove. Invalid shapeMode config: warning in logs + fallback to full. Preload: only in commonSetup via ShapeCacheWarmup (no more double warm-up on client + server). Rendering: cutout by default, translucent for barriers (barrierstone, barrierwood, etc.). Gradle: org.gradle.daemon=true.
