whn09 42e05844d1 Neuron: nkilib rotational_topk for the sampler; single-host shared engram tables (#27) 
- deep_select.topk on a NeuronCore with k >= 1024 (the sampler's force_topk
  4096 over the 129280 vocab) uses nkilib's rotational_topk: torch.topk with
  that k does not compile on the device (NCC_IXCG857). 8.4 ms on one core,
  values identical to torch.topk.
- EngramBuffer on Neuron: the ranks of a trn2 instance share one host, so the
  table shards are written into /dev/shm-backed tables (unlinked once mapped)
  and every rank gathers its own rows: no all-to-all and no host sync on split
  sizes per fetch. DEEPINFER_NEURON_ENGRAM_SHARED=0 restores the sharded path.
  Host EP=2 tiny: logits bitwise equal to the sharded path.
