- Route block/entity/item/packet/metadata palettes to new 1219 variants
for protocol >= 773, and raise upper-bound guards from MC_1_21_7 to
MC_1_21_9 so terrain, inventory, and entity handling are enabled.
- Add DataTypes readers for three new entity metadata serializer types:
CopperGolemState and WeatheringCopperState (both VarInt), and
ResolvableProfile (composite: Either<GameProfile, Partial> with
optional name/UUID/properties + PlayerSkin.Patch with 4 optional
fields for body/cape/elytra texture ResourceLocations and model type).

1.21.7 and 1.21.8 share protocol 772. The only registry change from
1.21.6 is one new item (music_disc_lava_chicken). All other palettes
(blocks, entities, packets, entity metadata, structured components)
are unchanged and reuse 1.21.6 versions.
Changes:
- Add MC_1_21_7_Version (772) constant
- Add "1.21.7" / "1.21.8" version mappings in ProtocolHandler
- Add MusicDiscLavaChicken to ItemType enum
- Generate ItemPalette1217 (1416 items) for the new item palette
- Update all version upper-bound checks from MC_1_21_6 to MC_1_21_7
- Update MCHighestVersion to "1.21.8"
Made-with: Cursor
- ItemPalette1216: 1415 items (generated from decompiled Items.java)
- EntityPalette1216: 151 entities (HappyGhast at index 56, all after +1)
- Palette1216: block states (DriedGhast 32 states at 13826-13857, all after +32)
- PacketPalette1216: clientbound +3 (Waypoint, ClearDialog, ShowDialog),
serverbound +2 (ChangeGameMode at 0x04 shifting all after, CustomClickAction at end),
config clientbound +2 (ClearDialog, ShowDialog),
config serverbound +1 (CustomClickAction)
- Version routing in Protocol18.cs, PacketType18Handler.cs, EntityMetadataPalette.cs
updated to select 1216 palettes for protocol >= 771
- EntityMetadataPalette reuses 1215 (EntityDataSerializers unchanged)

Add complete protocol 769 support for Minecraft 1.21.4:
- Version constants: Add 769 to supported versions, MC_1_21_4_Version constant,
and version string mappings (including 1.21.3 -> 768 compatibility)
- Item palette: 10 new items (Resin series + Eyeblossom), generated ItemPalette1214
- Entity palette: Remove CreakingTransient (149 entities, down from 150)
- Block palette: 10 new blocks with correct blockstate ID ranges from server data
- Packet palette: Serverbound packet ID reshuffling - PickItem split into
PickItemFromBlock/PickItemFromEntity, new PlayerLoaded packet inserted after
PlayerInput, subsequent IDs shifted accordingly. Clientbound unchanged.
- PlayerLoaded: Send empty PlayerLoaded packet after JoinGame processing (>= 1.21.4)
- EntityMetadata/DataComponents: Reuse 1.20.6 palettes (unchanged registries)
- Update all version guard checks from MC_1_21_2 to MC_1_21_4

1.20.6 introduced three new EntityDataSerializer types compared to 1.20.4:
- PARTICLES (id 18) - list of particles, inserted after PARTICLE
- WOLF_VARIANT (id 23) - wolf variant holder, inserted after CAT_VARIANT
- ARMADILLO_STATE (id 28) - armadillo state, inserted after SNIFFER_STATE
These insertions shifted subsequent serializer IDs, causing the 1.19.4
palette (EntityMetadataPalette1194) to misidentify metadata types on
1.20.6+ servers. This could lead to incorrect byte consumption and
potential packet parse failures when entities with affected metadata
types (e.g. wolves, armadillos, area effect clouds with particles)
were present.
Changes:
- Add Particles, WolfVariant, ArmadilloState to EntityMetaDataType enum
- Create EntityMetadataPalette1206 with correct 31-entry ID mapping
- Route 1.20.6+ to the new palette in EntityMetadataPalette.GetPalette()
- Add read logic for the three new types in DataTypes.cs
Verified on 1.21.1 vanilla server: cat, wolf, frog, armadillo, painting
entities all spawn without metadata parse errors.
