Module kernels 

Custom CubeCL kernels for swarm-algorithm hot paths.

Two kernels live here, both gated behind the crate-level custom-kernels feature:

• pairwise_attract_cube — fuses Firefly’s O(N²D) attractiveness update into a single launch that streams over neighbours to keep memory O(ND).
• levy_flight_cube — fuses Mantegna’s three-op Lévy-stable sampler into one launch. Wired into super::cuckoo and optionally super::bat only when profiling shows it on a hot path.

When custom-kernels is off, the super::firefly module caps population at N ≤ 128 and emits the pure-tensor O(N²D) decomposition; super::cuckoo and super::bat fall back to pure-tensor Mantegna sampling built from Tensor::random_normal + element-wise ops.

Modules
