Balanced Crafting Recipes

Fix

• Beacon (glass key pointed to an invalid tag → now works)
• Copper ingot/nugget recipes (were outside the recipe folder and never loaded)
• Stone Brick Stairs → Stone Bricks (broken pattern)
• Iron Chain → Iron Nugget (smelting & blasting; updated to renamed iron_chain)
• Glass Pane → Glass Block result

Add

• Shelf recipes for all 12 wood types (6 shelves from 6 logs/stems)
• Plain Glass usable directly in the universal glass dyeing recipes (all 16 colors)

Misc

• Lowered min pack format to 88 (now supports ~1.21.6 – 1.21.11)
