Better enchant tables

The mod adds the mending enchantment to tools and weapons offered by the enchanting table, and lets axes receive sharpness the way swords already do. Enchantment levels follow the item, so a gold tool can roll higher-tier options, and the odds for each possible enchantment match the ones used for swords. Both additions use the default rates and only apply to items they modify. Fabric API is required alongside it, and the environment is client and server, so the server and every player need the mod.
