Module compute_g_beta 

Fused GPU kernel for DeltaNet g and beta computation.

g[t, vh] = softplus(alpha_logit[t, vh] + dt_bias[vh]) * (-ssm_a[vh]) beta[t, vh] = sigmoid(beta_logit[t, vh])

Replaces the CPU bridge in compute_g_and_beta_cpu. For seq=1 this dispatches 1×nv threads — trivial GPU work but eliminates 2 CPU-GPU buffer downloads (alpha_logit, beta_logit) per delta-net layer.
