4cda9d54f3 feat(audio): add WASAPI FFI bindings for Windows audio output 
Implements COM vtable structs for IMMDeviceEnumerator, IMMDevice,
IAudioClient, and IAudioRenderClient with correct IUnknown base layout.
WasapiDevice handles COM init, default endpoint activation, mix format
detection (float/i16), shared-mode Initialize (50ms buffer), and
write_samples with GetCurrentPadding/GetBuffer/ReleaseBuffer.

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.
