whn09 3629d113fb Neuron: prompt chunks through the decode region graphs (issue #26)
- PrepareArgs.prompt_as_decode: decode-layout metadata for a prompt chunk;
  input_ids are the prompt's own tokens instead of last token + MTP drafts.
- DEEPINFER_NEURON_PREFILL_BUCKET adds one graph size; the model runner pads
  a prompt chunk to it with the decode placeholders (every EP rank takes the
  same bucket, so the static collectives match). Sampling still sees a prompt
  step.
- nki_attention.paged_mqa_logits: one gather + one kernel call for a chunk
  (one sequence) instead of a T-way loop.
- bf16 linear for the LM head eagerly on a NeuronCore (b.float() was a
  2.6 GiB copy a call); DEEPINFER_NEURON_REGION_TIMING; --num_prompts.

Host mode, tiny V4.1, chunk 128: same tokens as eager prefill (short 9/9,
long 715 tokens in 6 chunks 8/9 against golden).
