Follow-up to https://gitcode.com/cann/ops-nn/issues/2749

跟踪 issue https://gitcode.com/cann/ops-nn/issues/2749 复测时发现的、与原 BUILD/INSTALL/RUN 失败不同的新故障。
原 issue 报告的失败已被修复方案恢复，但下列示例在运行期出现新报错：

• 仓：ops-nn
• 算子：quant_batch_matmul_v3
• SOC：ascend950
• 触发场景：跑 ops-nn 的 phase1 examples（build/install 已成功）

失败示例

• quant_matmul_v3_at2_at3_int4
• quant_matmul_v4_at2_at3_int4
• quant_matmul_weight_nz_at2_at3_int4

本地环境

• CANN: 见仓内 README
• 修复方案（已对原 issue 应用）：clean → rm -rf scripts/kernel/binary_script/kernel_meta_*

烦请看一下这几个 int4 / 新路径变体在 ascend950 上是否预期支持，谢谢。
