线性回归

确认连续目标、解释变量和分析口径，检查缺失、异常、共线性与残差假设。报告拟合与验证指标、系数方向和不确定性；明确相关关系不等于因果关系。

Use get_schema to identify the continuous target, candidate predictors, and source table.
Use query_data to verify field names, missingness, outliers, and whether the target is numeric.
Use run_analysis with analysis_name="Regression" for the actual regression computation.
Use generate_chart on coefficient, residual, or prediction result tables after run_analysis succeeds.
