Kosinkadink	fd79f22bdf	Backport Hunyuan 3D 2.1 attention batch-size fixes from #13699 ... CrossAttention.kv.view and Attention.qkv_combined.view both hardcoded batch=1 in the reshape, crashing or silently mis-shaping whenever the actual batch dimension was greater than 1. These were fixed on master in #13699 as part of the same patch that gated the chunk(2) swap, but worksplit-multigpu only picked up the chunk(2) gate. Bring the two view() fixes over so we have parity with master.

Kosinkadink	019261ed96	Simplify Hunyuan 3D 2.1 swap_cfg_halves gate to a shape check ... The previous gate (len(cond_or_uncond) == 2 and set == {0, 1}) was intended to skip the cond/uncond swap when only one half was present under MultiGPU CFG Split, but it was too restrictive: it also skipped batch_size > 1 + CFG (cond_or_uncond like [0, 0, 1, 1] or [0,0,0,0, 1,1,1,1]), where chunk(2) still splits the batch cleanly into a cond half and an uncond half and the swap is still required. Switch to context.shape[0] >= 2, matching the parallel fix landed on master in #13699. The swap is a permutation-invariant no-op when the two halves don't form a CFG pair (since the output swap_cfg_halves block immediately undoes the permutation), so the only thing the gate actually needs to do is guard against chunk(2) on a batch of one.
