  Causal Depthwise Conv1D (Mamba/SSM)
  Core operator in Mamba state-space models. Each channel is convolved
  independently with a causal filter: y[b,d,t] = bias[d] + Σ weight[d,k] *
  x[b,d,t-k], left-zero-padded for causality. Single dynamic Helion kernel
  specializes only on filter width W (unrolls the inner loop) while B, D, N stay
   dynamic — cutting JIT compilations from 8 down to 3, solving a 12-min CI
  timeout. Config autotuned on Nebius B200.
