Native limbo protocol data / provenance

Packet IDs and typed registry captures for protocols 764-775:
PrismarineJS/minecraft-data, commit 8c6525b6cc0df0e218d01824d724017222e9b05e.

Attribution: minecraft-data contributors. The upstream README declares MIT and
notes that some data originated from wiki.vg / minecraft.gamepedia.com.

Animal variants: vanilla data extracted by misode/mcmeta, tags 1.21.5-data,
1.21.6-data, 1.21.9-data. https://github.com/misode/mcmeta
These are Minecraft registry data, not implementation code. No separate MIT
license is asserted for Mojang's game data. Minecraft belongs to Mojang/Microsoft.

Captures are reduced to a void overworld (min_y 0, height 256), plains, mandatory
damage/chat entries and required variants/sound/item-reference entries. Server
spawn conditions and unused timeline references are removed. Unknown protocols
are rejected explicitly; no runtime download or last-version guessing is used.

26.2 (776) registrations and login layout were checked against Mojang's official
26.2 server (bundler SHA-1 823e2250d24b3ddac457a60c92a6a941943fcd6a). Its codecs
validated reduced registries, block tags, login, position, all 16 chunk sections
and the inline dialogs. 26.1 and 26.2 sections require an extra fluid-count short.
All supported dialog clients (1.21.6+) send length-prefixed optional NBT, NOT
Boolean + NBT (checked in official 1.21.6, 1.21.9, 1.21.11 and 26.x codecs).
No Mojang executable classes or LimboAPI implementation are bundled in AxoLogin.
