Saphire mod

• Adds a new endgame Saphire material with craftable gem (diamond + lapis lazuli + netherite scrap) used for tools and repairs.
• Tool lineup: sword, pickaxe, shovel, axe, and hoe with very high durability, mining level 5, fast speed, and fireproof construction. Items appear in the default combat/tools tabs.
• Unique enchantments and matching enchanted books (craftable with a book, a Saphire gem, and the netherite version of the tool):
  • Saphire Edge (sword): extra strike damage plus weakness and slowness on hit.
  • Deep Quarry (pickaxe): grants Haste and extra XP from ore blocks.
  • Wind Scoop (shovel): speed boost while digging, bonus flint from gravel, and extra drops from soft blocks.
  • Timber Call (axe): adds Strength and fells up to two extra connected logs above the block you break.
  • Gentle Harvest (hoe): mature crops auto-replant at age 0, dropping extra seeds and giving brief saturation.
• All books use the enchanted book item model; if a stack is ever missing its stored enchantment, it refreshes itself automatically.
• Recipes, tags, models, and textures are bundled so the items work out-of-the-box on a Fabric 1.20.1 server.
