tnthack

• Adds a new shaped crafting recipe that lets you craft 1 TNT by filling a 3×3 crafting grid with dirt blocks (nine dirt total).
• Mod ID: tnthack; runs on both client and server for Minecraft 1.21.1.
• Implementation uses a data pack recipe plus a minimal initializer that logs when the mod loads; no commands or configuration are required.
• Limitation: recipe output is fixed at 1 TNT per 9 dirt and only available via a crafting table; there are no in-game toggles.
