b5a6159526 feat(renderer): add ShadowMap, shadow depth shader, and shadow pipeline 
Implements ShadowMap (2048x2048 Depth32Float texture with comparison sampler),
shadow_shader.wgsl (depth-only vertex shader), shadow_pipeline (front-face
culling, depth bias constant=2/slope=2.0), and associated uniform types.

62f505c838 fix(renderer): align LightsUniform to match WGSL vec3 padding (1056 bytes) 
WGSL vec3<f32> requires 16-byte alignment, causing the shader to expect
1056 bytes while Rust struct was 1040. Added padding fields to match.

fdfe4aaf5f feat: add multi-light demo with orbiting point lights and spot light 
Fix pbr_demo to use LightsUniform/LightData instead of old LightUniform.
Create multi_light_demo with 5 PBR spheres (varying metallic), a ground
plane, 4 colored orbiting point lights, a directional fill light, and a
spot light from above.

07497c3d80 feat: add PBR demo with metallic/roughness sphere grid 
7x7 grid of spheres demonstrating PBR material variation:
metallic increases along X axis, roughness along Y axis.
Uses dynamic UBO pattern for both camera and material uniforms.

ecf876d249 fix(many_cubes): use dynamic uniform buffer for per-entity rendering 
Previous approach called write_buffer inside render pass which doesn't
work — GPU only sees the last value at submit time. Now pre-computes all
entity uniforms into a dynamic UBO and uses dynamic offsets per draw call.

81ba6f7e5d feat: implement Phase 1 foundation - triangle rendering 
- voltex_math: Vec3 with arithmetic ops, dot, cross, length, normalize
- voltex_platform: VoltexWindow (winit wrapper), InputState (keyboard/mouse),
  GameTimer (fixed timestep + variable render loop)
- voltex_renderer: GpuContext (wgpu init), Vertex + buffer layout,
  WGSL shader, render pipeline
- triangle example: colored triangle with ESC to exit

All 13 tests passing. Window renders RGB triangle on dark background.
