c0c4c078c0 fix: use HashedStack for container_click and fix enchantments parsing for 1.21.5+
Two bugs fixed:

1. EnchantmentsComponent was reading a trailing ShowTooltip boolean that
   was removed from the wire format in MC 1.21.5. Created
   EnchantmentsComponent1215 and StoredEnchantmentsComponent1215 that
   omit the boolean. Used by StructuredComponentsRegistry1215 and 12111.

2. MC 1.21.5+ changed ServerboundContainerClickPacket to use HashedStack
   (item holder id + count + hashed component patch map) instead of full
   ItemStack for changed slots and carried item. Added GetHashedItemSlot()
   in DataTypes.cs and gated SendWindowAction in Protocol18.cs to use it
   for 1.21.5+. Since MCC doesn't track component hashes, an empty
   HashedPatchMap is sent; the server detects stateId mismatch and resyncs.

Tested: AutoFishing bot successfully catches fish on MC 1.21.11 with
enchanted fishing rods (Lure III + Luck of the Sea III).
