* ggml: add ggml_build_forward_order ggml_build_forward_expand marks the tensor and all its ancestors for compute, so using it as a pure ordering hint (keeping q, k and v together) defeats ggml_build_forward_select: the unselected branch is forced to run with inputs that were never uploaded. In the mtmd audio graph this makes GEN_WAV calls execute the GEN_CODE branch with a stale inp_code0, hitting the get_rows bound assert on CPU. Add ggml_build_forward_order, which inserts nodes without the compute flag; the flag is restored when the branch is actually selected. Switch the q/k/v hints in clip_graph::build_attn to it. * nit: reduce comments (AGENTS.md)
