截尾处理

先定义异常判据和业务合理范围，量化拟删除样本及其特征。仅在用户意图明确时执行，保留原始数据和可追溯输出；处理后报告样本损失及潜在选择偏差。

Use get_schema to identify the target table and candidate numeric columns.
Use profile_data to quantify outliers and candidate trim boundaries before modification.
Use clean_data with the trimming operation only when the user has confirmed the rule or bounds.
Use query_data after cleaning to verify row loss, boundary effects, and key metric changes.
