feat: 3 dynamic point lights with shadows

Browse Source 
- MainLight: warm (1.0, 0.95, 0.85), intensity 12, range 60
- SecondLight: cool blue (0.3, 0.6, 1.0), intensity 8, range 40
- ThirdLight: red (0.9, 0.2, 0.3), intensity 8, range 40
- All 3 orbit in chaotic circles at different phases
- All 3 cast shadows (18 shadow passes per frame = 3 × 6)
- ImGui: per-light sliders for all 3 lights
- Reduced intensities slightly to balance 3 overlapping lights
