whn09 fdbb81f14f Neuron DSpark (#15): draft layers and main-cache writes as region graphs, decode rows padded to a power of two
- DFlash forward_drafts per layer and update_main_cache (projection, then each
  layer's cache write) run as region graphs: eagerly the fp8 cast of the
  projection norm does not compile.
- neuronx-cc rejects the sparse decode attention at 6 rows (a DSpark step with
  5 drafts; ISA validation 'same_element_count_t2d'), 4 and 8 rows compile:
  multi-row decode steps pad to a power of two with empty rows.
- bench_neuron.py --nextn: DSpark drafts, reports tokens per decode step.
- Tiny checkpoint on device, cp=2, free-running greedy with drafts: nextn=3,
  5, 7 all 9/9 golden tokens (short), nextn=5 long 9/9.
