Quartz

Block registration rewrite

• BlockRegistry.block() — register a block with BlockItem using configureBlock {} / configureItem {} DSL. Supports customBlock(::MyBlock) and customItem { block, props -> ... }.
• BlockRegistry.stair(baseBlock, …) / BlockRegistry.slab(baseBlock, …) — register stair/slab with full datagen (models, blockstate, loot table, tag). Accepts Block, DeferredBlock<*>, or BlockWithItem<*,*> as base.
• BlockRegistry.wall(baseBlock, …) — register a wall with post/side/side-tall/inventory models, auto-registers #walls.
• BlockRegistry.fence(baseBlock, …) / BlockRegistry.fenceGate(baseBlock, …) — register fence and fence gate with 4-way blockstate, auto-registers #fences/#fence_gates.
• BlockRegistry.button(baseBlock, …) / BlockRegistry.pressurePlate(baseBlock, …) — register button/pressure plate with BlockSetType and ticks (button only).
• BlockRegistry.door(…) / BlockRegistry.trapdoor(…) — register door/trapdoor with BlockSetType, full cutout model gen, and conditional loot.
• BlockRegistry.flower(baseBlock, …) / BlockRegistry.tallFlower(baseBlock, …) — register one-block/two-block flower with FlowerPotBlock registration and potted model.
• BlockRegistry.torch(…) — register a wall-mountable torch with particle texture.
• BlockRegistry.snowLayer(baseBlock, …) — register an 8-layer snow-like block with layered loot.
• BlockRegistry.pillar(baseBlock, …) — register RotatedPillarBlock with cube_column model (end/side textures).
• All block types expose configureBlock {}, configureItem {}, texture("path"), and toggle flags (blockState, lootTable, renderType).
• New BlockBuilder class — configureBlock {}, configureItem {}, customBlock(::MyBlock), customItem { block, props -> ... }.
• New block.noCollision() extension function for block properties.

Item registration

• ItemRegistry.item(config) — register any item with model datagen. Supports configureProperties {}, texture("path"), model = true/false, customItem { props -> ... }.
• ItemRegistry.sword(tier, …), pickaxe(tier, …), axe(tier, …), shovel(tier, …), hoe(tier, …) — register tools with parameterized attackDamage/attackSpeed, handheld model, and vanilla enchantability tags.
• All item types support model, customTexture, configureProperties {}.

Datagen

• DatagenPlan interface — each block type emits its own blockstate, loot table, and tags via emitBlockState(), emitLootTable(), emitTags().
• LootTableContext — helpers: dropSelf(), dropSlab(), dropLayered(), dropOther(), addLootTable().
• TagContext — helpers: add(tag, block), add(tag, item).
• Datagen auto-registers in @Mod class via QuartzDataGatherers.register(modEventBus) — no manual GatherDataEvent listener needed.
• Datagen groups providers by modId, supporting multiple registries per mod.

Infrastructure

• IRegistry interface — both BlockRegistry and ItemRegistry implement it for uniform register(bus).
• bindName delegate — property name → snake_case name resolution for all registration functions.
• BlockWithItem is now a data class with blockHolder / itemHolder fields and convenience block / item accessors.
