BruceChen 8eac21b4a4 Wire up 1.20.6 structured components to Item and fix GetItemSlot serialization
In 1.20.6+, items use structured components instead of NBT for metadata.
Previously, ReadNextItemSlot parsed the components but never stored them
on the Item instance, leaving DisplayName/Lores/Damage/Enchantments all
empty. GetItemSlot also still used the pre-1.20.6 format (bool + VarInt +
byte + NBT), causing the server to reject any item operation packets.

Changes:

Item.cs:
- Add List<StructuredComponent>? Components field to hold the raw
  component list for round-trip serialization
- DisplayName property: read from CustomNameComponent (with
  ItemNameComponent as fallback) when Components is present
- Lores property: read from LoreNameComponent1206 when Components is
  present
- Damage property: read from DamageComponent when Components is present
- Add EnchantmentList property: read from EnchantmentsComponent (covers
  both normal and StoredEnchantmentsComponent for enchanted books)
- ToFullString(): use EnchantmentList with EnchantmentMapping for display
  when available, fall back to NBT path for older versions
- Add CloneWithCount() method that preserves both NBT and Components

DataTypes.cs - ReadNextItemSlot:
- Assign parsed strcturedComponentsToAdd to item.Components

DataTypes.cs - GetItemSlot:
- Add 1.20.6+ branch: write VarInt(count) + VarInt(itemId) + component
  counts + serialized components (using each component's TypeId and
  Serialize() method)
- Empty slot sends VarInt(0) per the 1.20.6 protocol spec

StructuredComponent.cs:
- Add int TypeId property (default -1) to store the registry type ID
  assigned during parsing, enabling round-trip serialization

StructuredComponentRegistry.cs:
- Set component.TypeId = id after instantiation in ParseComponent()

McClient.cs:
- Replace manual Item constructor calls (new Item(type, count, nbt))
  with Item.CloneWithCount() to preserve Components during inventory
  operations like slot moves, stack splits, and right-click placement
