feat: add packet palette, data components, and protocol fixes for MC 1.21.2
Packet Palette (Phase 2.1):
- Create PacketPalette1212.cs with complete ID mapping for protocol 768
(131 clientbound + 60 serverbound play packets, plus config packets)
- Add new PacketTypesIn enum values: EntityPositionSync, MoveMinecartAlongTrack,
PlayerRotation, RecipeBookAdd/Remove/Settings, SetCursorItem, SetHeldSlot,
SetPlayerInventory
- Add new PacketTypesOut enum values: BundleItemSelected, ClientTickEnd
- Update PacketType18Handler routing for 1.21.2
Data Components (Phase 1.4):
- Create StructuredComponentsRegistry1212 with 67 components (was 57 in 1.21)
reflecting the new 1.21.2 DataComponents ordering
- Implement 11 new component parsers: ConsumableComponent, UseRemainderComponent,
UseCooldownComponent, DamageResistantComponent, EnchantableComponent,
EquippableComponent, RepairableComponent, GliderComponent, TooltipStyleComponent,
DeathProtectionComponent, ItemModelComponent
- Create FoodComponent1212 (simplified: nutrition/saturation/canAlwaysEat only;
eatSeconds/effects/usingConvertsTo moved to consumable/use_remainder)
- Create SubComponentRegistry1212 and route in StructuredComponentsHandler
Protocol Fixes:
- Fix PlayerPositionAndLook packet for 1.21.2 (new format: teleportId first,
added deltaMovement Vec3, flags as Int instead of Byte)
- Fix login success packet (remove strictErrorHandling read for >= 1.21.2)
- Fix ClientSettings/ClientInformation packet (add particleStatus VarInt)
- Add SetHeldSlot as alias for HeldItemChange in packet handler
Verified: MCC connects to 1.21.2 vanilla server, stays connected, chat works.
