lightning enchant

Lightning Shot adds a single-level enchantment for maces and all sword tiers. An enchanted hit calls down a vanilla lightning bolt on the struck mob.

• The enchantment is registered via the 1.21 definition API and limited to the hand slots for swords/mace, so it cannot be applied elsewhere. It appears in the Combat creative tab as a ready-made enchanted book.
• Attack handling listens to AttackEntityCallback on the server; if the attacker’s held item carries Lightning Shot, the target is struck by lightning at mid-height. Channeler is set when a server player attacks so advancement/credit flows correctly.
• Costs/weight are tuned for standard table rolls (weight 10, single level, moderate enchant/anvil costs).

Known limitations and notes:

• Only fires on direct melee swings; projectiles or indirect damage won’t trigger it.
• Lightning uses vanilla behavior (damage, fire setting, and weather checks), so expect normal fire spread and pig/zombie-piglin conversions in overworld conditions.
