Replace '== null' with 'is null' and '!= null' with 'is not null'
across 19 core files following modern C# pattern matching conventions.
Only literal null comparisons are changed. Assignments, value
comparisons, and LINQ expressions are left untouched.

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
Made-with: Cursor
* Implement MC version 1.16.2 basic support
All packets ID update done
Tested in 1.16.2 craftbukkit server
* Implement MC 1.16.2 entity handling
New EntityPalette
* Add back protocol version checking for entity handling
Was removed during testing and forgot to add it back
* Implement inventory handling for MC 1.16+
Item ID got changed in 1.16+ so a palette is needed.
* Fix ChangeSlot command
What a joke
* Handle 1.16 new entity properties name
Convert new naming style to old style
* Revert "Handle 1.16 new entity properties name"
This reverts commit 52c7d29062.
* Update AutoAttack to use the new entity properties key
* Fix item type to ID conversion
* Sort item types by name
* Remove ZombiePigmanSpawnEgg
User ZombifiedPiglinSpawnEgg instead (new name for same item)
* Add missing 1.16.2 version strings
* Remove old ItemTypeGenerator
* Sort entity types by name
* Palette loading, instructions, NotImplemented err
