feat(sdk): publish npc type id on NearbyNpc

Filters written as npc.id === configId were comparing undefined === n and
failing silently - NearbyNpc only carried the world slot (index) and name,
unlike every other published entity. Surface NpcType.id (npc.pack config
id) on both the collector and the SDK type.
