Breaking Change: Item access now always returns and stores copies (#26)

• All item getters return a copy of the underlying item. Modifying the returned value does not affect the original.
• All item setters store a copy of the provided item. The original value passed in is not consumed or modified.
• Migration: Code that relied on in-place modification of item references must now write the value back explicitly. For example:

  -- Before (no longer works):
  local item = player:getItemInHand("MAIN_HAND")
  item.count = 5  -- had an effect on the actual item in hand
  -- After (correct):
  local item = player:getItemInHand("MAIN_HAND")
  item.count = 5  -- has NO effect on the actual item in hand
  player:setItemInHand("MAIN_HAND", item) -- NOW affects the item in hand
  

• Affected APIs: LivingEntity:getItemInHand(), LivingEntity:setItemInHand(), LivingEntity:getEquipment(), LivingEntity:setEquipment(), Player.mainHandItem, PlayerInventory[slot], Entity:dropItem(), ItemEntity:new(), ItemEntity.item.

New: spell.world is now writable (#25)

• Assign a world to move a spell to a different dimension:

  spell.world = spell.server:getWorld("the_nether")
  

• Chunk-force tickets are correctly transferred when the spell changes worlds.

New: Server.worlds

• Read-only list of all currently loaded server worlds.

New: World.timeOfDay

• Read-only property returning the current time-of-day tick (0–23999).

Fix: and/or short-circuit chain returns wrong result when condition is a comparison (#27)

• Upgraded the internal Lua runtime (rembulan 0.3.2) which contains the fix for this logic bug.
