Fix world border speed: varlong, not varint (regressed in 1.19)
ClientboundInitializeBorderPacket and ClientboundSetBorderLerpSizePacket encode the border lerp time as a VarLong in vanilla (long lerpTime, writeVarLong/readVarLong). minecraft-data had speed correct as varlong in 1.17-1.18.2, but it regressed to varint in 1.19 and was never fixed - wrong for every version from 1.19 to 1.21.11. VarInt and VarLong encode identically below 2^28 ms (~74h), so this only breaks on long (multi-day) border interpolations, where the multi-byte VarLong mis-parses as a VarInt. Verified readVarLong/writeVarLong against the Mojang server jars for 1.19.4 and 1.21.3-1.21.9. proto.yml edited, protocol.json regenerated with npm run build.
