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 constants for MC 1.21.2 (protocol 768)
Add item, entity, block, and metadata palettes for Minecraft 1.21.2:
- ItemPalette1212: 1375 items (42 new: pale oak set, colored bundles,
creaking heart/spawn egg, banner patterns)
- EntityPalette1212: 150 entity types (boats split into per-wood-type
entries, generic boat/chest_boat removed; added creaking,
creaking_transient, pale oak boats)
- Palette1212 (blocks): 1084 block types with state IDs generated from
official 1.21.2 data reports (24 new pale oak blocks, creaking heart,
pale moss variants)
- EntityMetadataPalette: reuses 1206 (serializers unchanged in 1.21.2)
Updated version infrastructure:
- Protocol18.cs: MC_1_21_2_Version = 768, palette switch routing
- ProtocolHandler.cs: version mapping 1.21.2 <-> 768
- Program.cs: MCHighestVersion bumped to 1.21.2
- ItemType.cs, EntityType.cs, Material.cs: new enum entries
Note: packet palette, structured components, and protocol handler
changes for 1.21.2 are not yet implemented — this commit covers
palette/registry groundwork only.
