Enables MUL_MAT with K>ROCKET_K_MAX (e.g. gemma-4 ffn_down K=12288) on the NPU via 6144-wide K-chunks, mirroring ggml-rknpu2 compute_k_segments. Validated correct (coherent long-prompt greedy output; int8 2-way partials lossless enough). pp512-NEUTRAL on gemma-4-E2B (46.61 vs 46.69) — kept on a branch as a capability, not defaulted. May help models with heavy K>8192.
