Module kernels 

Built-in compute kernels as embedded GLSL source strings.

Each kernel is a fully implemented GLSL compute shader. The Rust side provides parameter structs and convenience methods to compile and dispatch each kernel through the dispatch module.

Kernels:

1. particle_integrate — position += velocity * dt, apply forces, age, kill dead
2. particle_emit — atomic counter for birth, initialize from emitter params
3. force_field_sample — evaluate multiple force fields at particle positions
4. math_function_gpu — Lorenz attractor, Mandelbrot iteration, Julia set
5. fluid_diffuse — Jacobi iteration for diffusion
6. histogram_equalize — compute histogram and equalize
7. prefix_sum — Blelloch parallel prefix sum (scan)
8. radix_sort — GPU radix sort
9. frustum_cull — per-instance frustum culling
10. skinning — bone matrix palette skinning
