jgrusewski f77ebeb214 perf(htod): migrate gpu_iqn_head.rs to mapped-pinned + DtoD-only clone (5 sites)

- 4 stream.clone_htod sites in IQN constructor: cos_features precompute,
  online_taus + target_taus tile broadcast, init_iqn_xavier_weights
  upload — all rewritten to mapped_pinned::clone_to_device_f32_via_pinned.
- clone_cuda_slice helper rewritten to a single DtoD copy via the
  existing super::clone_cuda_slice_f32 helper. Previously did
  device→host→device, double-violating both no-DtoH and no-HtoD rules.
  Sole callsite is constructor seeding of target params from online.

Audit row appended (Fix 9) in docs/dqn-gpu-hot-path-audit.md.
