Enchantment Overhaul

Changes

• Every enchantment has its own reagent and price curve, matched to its theme and power. Endgame enchantments ask for endgame materials: Mending takes Ghast Tears, Swift Sneak Sculk Sensors, Lunge Wind Charges, Looting Rabbit Feet and Infinity Spectral Arrows. Bookshelves still cut costs by up to half, and upgrading in steps costs exactly as much as applying the level directly.
• The grindstone no longer costs an enchantment slot. Items penalized by older versions get their slots back, and the anvil's slot restoration is gone.
• The anvil repairs every tool vanilla could only fix by combining two copies: bows, crossbows and fishing rods with string, tridents with prismarine shards, shears with iron, flint and steel with flint, the two sticks with their food, and brushes with feathers. Each material comes from an item tag datapacks can edit.
• Grinding templates now drop from dungeons and desert pyramids as documented.
• Veil no longer makes its wearer untargetable: phantoms attack again, mobs retaliate when hit and Endermen keep their aggro. It still cuts detection range to a quarter.
• The catalogue shows its inventory label and the real bookshelf discount, keeps your selected level while you add reagents, and books with two enchantments show both.
• Upgrade names, armor resistances, catalogue hints and /upgrade messages are translated, French included.
• The wiki is up to date with the current mechanics.
