Subject: [PATCH] Fix BlinkLight, WashLight, Spotlight3d to use material
 properties
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Stage light objects have no Unity Light components — they are
self-illuminated meshes. All three handlers now write to MeshRenderer
material properties instead.

BlinkLight: GetComponentsInChildren<Renderer> → _Color + _ColorPower.
pattern==0 uses per-renderer color0Array/powerArray; blink cycle
multiplies col * intensity into _Color.

Spotlight3d: adds _Color + _ColorPower writes after transform update.
color/colorPower fields were previously unused.

WashLight: sets _ProjectorColorPower from CameraProjectionColorPower
on projector materials. _ProjectorMulColor0 left at material default
(no color field in keyData).
