tolelom 1081fb472f feat(renderer): improve IBL with Hosek-Wilkie sky, SH irradiance, GPU BRDF LUT ...

- Hosek-Wilkie inspired procedural sky (Rayleigh/Mie scattering, sun disk)
- L2 Spherical Harmonics irradiance (9 coefficients, CPU computation)
- SH evaluation in shader replaces sample_environment for diffuse IBL
- GPU compute BRDF LUT (Rg16Float, higher precision than CPU Rgba8Unorm)
- SkyParams (sun_direction, turbidity) in ShadowUniform
