fix: add EntityMetadataPalette1206 for correct 1.20.6+ entity metadata parsing
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.

feat: add palettes and version routing for MC 1.21.6
- 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)
