whn09 ad6b47a141 Neuron: head-sharded attention over the CP group (TP decode) (#28)
With a CP group running one replicated batch (DEEPINFER_NEURON_TP_ATTN, on
when cp > 1), each rank keeps its heads' rows of q_b, its groups' slice of wv
(or its heads' columns of one group), the matching out_proj columns and its
attention-sink entries; _wv_and_o_proj all-reduces the partial outputs over
the group (exact: wv and out_proj are linear in the heads; asserts no clamp).
Q-a / KV / indexer / compressor stay replicated.

Host tiny (8 heads, 2 groups): cp=2 (1 group a rank), cp=4 (2 heads of a
group), cp=8 (1 head) all give the golden tokens up to near ties.
