Update packet ID mappings for 1.21.5 (protocol 770): Clientbound packets shifted -1 due to ADD_EXPERIENCE_ORB removal: - OpenWindow: 0x35 -> 0x34 - CloseWindow (CB): 0x12 -> 0x11 - WindowItems: 0x13 -> 0x12 - WindowProperty: 0x14 -> 0x13 - SetSlot: 0x15 -> 0x14 - SoundEffect: 0x6F -> 0x6E - HeldItemChange (CB): 0x63 -> 0x62 Serverbound packets shifted +2 due to new PLAYER_LOADED and BUNDLE_ITEM_SELECTED packets: - BlockPlacement: 0x3C -> 0x3E - UseItem: 0x3D -> 0x3F Also adds missing HeldItemChange clientbound mapping for 1.21.2-1.21.4 (0x63) which was previously absent. All packet IDs verified against ViaVersion's authoritative enum definitions (ClientboundPackets1_21_5 / ServerboundPackets1_21_5). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
