Module kernels 

GPU compute kernels (WGSL shaders)

Parallel Reduction Algorithm (Harris 2007):

1. Each thread loads one element
2. Workgroup-local reduction using shared memory
3. Global reduction of workgroup results

Performance: O(N/P + log P) where P = num threads

Functions

count

Execute COUNT aggregation on GPU Trivial implementation - just returns array length

max_i32

Execute MAX aggregation on GPU (i32)

min_i32

Execute MIN aggregation on GPU (i32)

sum_f32

Execute SUM aggregation on GPU (f32) Placeholder - not yet implemented

sum_i32

Execute SUM aggregation on GPU (i32)
