kernelize 的 NPU patch 无法生效，导致NPU forward被ep forward覆盖。考虑在ep forward中单独给NPU提供forward。ep forward原实现逐 expert Python 循环，在 EP 闭包内部复用现有 NPU 组件（GmmFunction + npu_swiglu + _get_cached_expert_weights）替换循环实现并行化。每次前向做资格检查，不满足条件自动回退原循环并打印一次 WARNING 说明原因。
端到端验证： loss 曲线与原实现一致，使用ep_fsdp2_lora_qwen3_5_moe.sh 设备2*910B 模型qwen3.5-35B-A3B 每 12 step 约 200s -> 60s。
二编：
改动代码结构，原有EP experts forward也收纳到kernel底下ops里面并且实现多impls管理。测试两种ep forward分支（NPU和逐expert循环）都能跑通，使用ep_fsdp2_lora_qwen3_5_moe.sh 设备2*910B batch8 模型qwen3.5-35B-A3B 16steps NPU时间185s，逐expert循环393s。
