Move the 3 decode CPU-pipelining variants (opt1 current / opt3 sw-pipe / opt2 ex_composite) up into the TL;DR as full standalone kernels alongside the full prefill ring kernel, with the comparison table. S5.6 is reduced to a brief anchor (still referenced by S8/SB) pointing to the TL;DR code + keeping the recommend/cost-model linkage. Docs only.
