whn09 0cae424dc4 Neuron: one KV gather per chunk for dense attention; no layer_idx guards (#26)
- nki_attention._chunk_attention: a prompt chunk run as a decode step gathers a
  dense compressed-KV scope once (every token's list is a prefix of the
  longest) and masks it per row; top-k and SWA scopes stay per row. The
  per-row gather was [128, 8192, 512] for a ratio-2 layer of the full model:
  3.8 GB moved per call and a 3 GB NEFF (model code) that ran HBM out.
- decode_part_timer: the decode timers are no-ops inside region graphs. Their
  f-string labels read layer_idx, so Dynamo guarded on it and retraced every
  layer instead of every layer kind.

Tiny V4.1 on a NeuronCore, bucket 128: short 9/9, long 9/9 (logit cos >= 0.997).
