Netherite Anvil & More Enchantments!

Fixed a Netherite Anvil bug where Unbreaking could not be applied to Elytra.

Reworked Glow Sight so Night Vision now applies and clears correctly based on helmet state.

Fixed cases where Glow Sight could remain active after unequipping the helmet or fail to reactivate after re-equipping it.

Increased Netherite Anvil block durability to roughly twice that of obsidian.

Netherite Anvil now requires a diamond pickaxe or better for proper harvesting and only drops itself when broken with the correct tool.
