+操作日志工具模块
+
+提供 @op_log 装饰器和 log_operation 函数，用于记录用户在各业务模块的详细操作。
+自动捕获成功/失败状态、完整报错堆栈、操作耗时等。
+
+核心设计：
+  - 失败操作必须清晰记录完整异常堆栈（traceback）
+  - 记录异常类型（如 RuntimeError / ValueError / ConnectionError）
+  - 记录具体出错的函数名和文件位置，方便定位 bug
+  - 记录 HTTP 状态码，方便区分用户错误(4xx)和系统错误(5xx)
+
+使用示例：
+    from app.core.op_log import op_log, OpModule, OpAction
+
+    @router.post("/inference/start")
+    @op_log(module=OpModule.INFERENCE, action=OpAction.START, target_type="inference")
