缩尾处理

识别目标数值字段和异常分布，说明上下界规则后再缩尾。不得默认覆盖原始数据；比较处理前后的分布、均值和关键指标，并记录边界与受影响行数。

Use get_schema to identify the target table and candidate numeric columns.
Use profile_data to quantify distribution tails before modification.
Use clean_data with the winsorize operation only after the percentile bounds are clear.
Use query_data after cleaning to verify clipped values, row counts, and key metric changes.
