Add a decoding capture proxy (tools/net_capture.py), an offline vanilla
client launcher (tools/vanilla_client.py) and a vanilla codec oracle that
decodes every captured clientbound packet with vanilla's StreamCodecs.
Fix the entity data serializer ids (vector3 onwards were off by one), the
sheep wool and piglin baby indices, send mob variants, villager data and
equipment, and send entity movement at each type's update interval and
tracking range with position syncs, like ServerEntity.sendChanges.
