Function _patch_kernels

modelscope/utils/hf_util/patcher.py:520–535

Monkey-patch the `kernels` library to route HF API calls to ModelScope. Only `kernels.utils._get_hf_api` is replaced; every download, file check and ref listing performed by `kernels` goes through `_MsKernelApi`, so the kernel loading/variant/lock logic stays untouched.
