🛠️ Engineering Table Update - Gun Crafting Overhaul

This update introduces a dedicated crafting station for firearms and traps, separating them from vanilla crafting to prevent recipe conflicts and add immersion.

✨ New Features

• Engineering Table: A new custom workstation required to craft all Guns and specialized Traps.
  • Crafting Recipe: Iron Ingot + Piston + Redstone + Crafting Table (Visible in Vanilla Recipe Book).
• Complex Gun Recipes:
  • Moved all gun crafting to the Engineering Table.
  • New "Lung Tung" Recipe System: Guns now require specific mechanical components as "Cores" (e.g., Pistons for Shotguns, Spyglass for Snipers, Hoppers for SMGs) combined with Iron, Gunpowder, and Redstone.
• Resource Pack Structure: Refactored internal assets to zombie_assets namespace for better compatibility and copyright safety.

🔧 Fixes

• Fixed texture pack model overrides not loading due to missing namespace folders.
• Optimized recipe registration to prevent console warnings on startup.
