Module fuse 

Dimension fusion logic ported from Strided.jl/src/mapreduce.jl

This module implements the core dimension fusion algorithm that merges contiguous dimensions to reduce iteration complexity.

Functions

compress_dims

Remove size-1 dimensions from fused dims and all corresponding strides.

compute_costs

Compute the minimum stride cost for each dimension.

compute_importance

Compute the “importance” of each dimension for loop ordering.

fuse_dims

Fuse contiguous dimensions across multiple arrays.

fuse_dims_bilateral

Bilateral dimension fusion for src + dst stride patterns.

sort_by_importance

Get the permutation that sorts by importance (descending).
