K-Means 聚类

确认聚类实体与特征，处理缺失值并标准化数值变量。比较合理的 K 值，报告聚类质量、各簇规模、中心特征和业务画像，并说明异常点及稳定性限制。

Use get_schema to identify the entity key, candidate numeric features, and source table.
Use query_data to verify feature availability, missingness, and scale before modeling.
Use run_analysis with analysis_name="K_Means" for the clustering computation.
Use generate_chart on cluster profiles, elbow output, or label result tables after run_analysis succeeds.
