Description:
Implement point lights and directional lights with proper light accumulation in PBR shader.
Tasks:

Create Light struct (position, color, intensity, type)
Add uniform buffer for light array
Update fragment shader to loop over lights
Implement point light attenuation
Implement directional light (infinite distance)
Add shadows support structure (prepare for future)
Create light manager/system
Test with multiple colored lights

Acceptance Criteria:

Multiple lights affect surfaces correctly
Point lights attenuate with distance
Directional lights illuminate uniformly
Light colors blend properly

Related Issues: Depends on #17
Estimated Time: 2-3 days
