Added

tool_required (optional): Restrict which tools/items can trigger the spawn (default: any item)

• If omitted, any item (including bare hands) can trigger the spawn
• Single item format: "minecraft:diamond_hoe" - Only diamond hoes trigger the spawn
• Array format: ["minecraft:diamond_hoe", "minecraft:netherite_hoe"] - Any of these tools trigger the spawn
• Should work with any Modded item: Use full item IDs with namespace (e.g., "minecraft:diamond_hoe", "farmersdelight:minced_beef")
• The player must be holding the required item in their main hand when breaking the block
