080ac92fbb fix(renderer): merge IBL into group(3) to stay within max_bind_groups limit of 4 
wgpu's default max_bind_groups is 4 (groups 0-3), but the PBR shader was
using group(4) for BRDF LUT bindings. This merges IBL bindings into the
shadow bind group (group 3) at binding slots 3-4, removes the standalone
IBL bind group layout/creation, and updates all examples accordingly.

5232552aa4 feat(renderer): add normal mapping and procedural IBL to PBR shader 
- Add tangent input (location 3) and TBN computation in vertex shader
- Add normal map sampling (group 1, bindings 2-3) for tangent-space normal mapping
- Add BRDF LUT binding (group 4, bindings 0-1) for specular IBL
- Add procedural sky environment function for diffuse/specular IBL
- Replace flat ambient with split-sum IBL approximation
- Add pbr_texture_bind_group_layout (4 entries: albedo + normal)
- Add create_pbr_texture_bind_group helper and flat_normal_1x1 texture
- Update create_pbr_pipeline to accept ibl_layout parameter (group 4)

ea8af38263 feat(renderer): add BRDF LUT generator and IBL resources 
Implements CPU-based BRDF LUT generation using the split-sum IBL
approximation (Hammersley sampling, GGX importance sampling, Smith
geometry with IBL k=a²/2). Wraps the 256×256 Rgba8Unorm LUT in
IblResources for GPU upload via wgpu 28.0 API.

5f962f376e feat: add shadow demo with directional light shadow mapping and 3x3 PCF 
- Add Mat4::orthographic() to voltex_math for light projection
- Fix pbr_demo and multi_light_demo to provide shadow bind group (group 3)
  required by updated PBR pipeline (dummy shadow with size=0 disables it)
- Create shadow_demo with two-pass rendering: shadow depth pass using
  orthographic light projection, then PBR color pass with shadow sampling
- Scene: ground plane, 3 spheres, 2 cubes with directional light

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.
