Register dat-defined LightInfos as runtime LightSources when entities
stream in. Every Setup (0x02xxxxxx) with a non-empty Lights dictionary
gets its per-part lights pulled via LightInfoLoader, which converts
the local Frame + ColorARGB + Intensity + Falloff + ConeAngle fields
into world-space LightSource records owned by the entity id.
Wire the LightingHookSink into the animation-hook router so retail's
SetLightHook animations (ignite-torch, extinguish-lamp) flip the
matching LightSource.IsLit latches. One hook may own multiple lights
(lamp-posts with two LightInfo entries) — the sink maintains an
owner-indexed map so all get toggled together.
Unregister on landblock unload: the streaming controller's
removeTerrain callback grabs the loaded landblock's entity list (new
GpuWorldState.TryGetLandblock helper) and drops every owner from the
sink before the entities disappear — otherwise walking across
landblocks accumulates stale LightSources.
9 new tests (LightingHookSink routing + LightInfoLoader conversion).
