变更摘要
此 PR 将 LeftShift 算子的 TensorFlow 插件迁移至 ops-math 仓，新增了 math/left_shift/framework/left_shift_tf_plugin.cpp 文件，用于注册 LeftShift 算子的 TF 框架适配逻辑。
主要改动
- 新增
left_shift_tf_plugin.cpp文件：在math/left_shift/framework/目录下新建 TF 插件源文件，包含版权声明、头文件引用及算子注册实现。 - 实现
AutoMappingByOpFnLeftShift映射函数：该函数封装AutoMappingByOpFn实现算子自动映射，并在失败/成功时分别通过OP_LOGE和OP_LOGI输出日志。 - 注册
LeftShift算子为 TF 框架插件：通过REGISTER_CUSTOM_OP("LeftShift")宏将算子注册为TENSORFLOW框架的 AI_CPU 类型算子，指定原始算子类型为"LeftShift"并绑定解析函数。
代码审查
审查总结
本次变更文件共 1 个，已全部审查完毕：
math/left_shift/framework/left_shift_tf_plugin.cpp：发现 1 个 P3 问题（包装函数丢弃AutoMappingByOpFn的原始错误码，统一返回FAILED，可能损失错误诊断信息）。
发现问题按优先级统计：
- P0：0
- P1：0
- P2：0
- P3：1
整体风险评估：低风险。 该变更是一个新增的 TensorFlow 插件注册文件，结构与项目中已有的 arg_min_tf_plugin.cpp 模式一致。代码逻辑简单、无内存管理问题、无安全漏洞、无并发风险。唯一的 P3 问题是在错误路径上丢弃了原始错误码，属于轻微的错误处理精度问题，不影响功能正确性。
⚠️ 已识别出整体风险，但无法提取行内评论，请参考整体评估。
