决策树分析

确认目标变量和任务类型，排除泄漏字段，合理处理缺失值与类别变量。执行训练验证并报告性能、重要特征和可解释规则；避免把相关性表述为因果。

Use get_schema to identify the target, candidate features, task type, and source table.
Use query_data to verify field names, target distribution, missingness, and leakage risks.
Use run_analysis with analysis_name="Decision_Tree" for the actual tree computation.
Use generate_chart on tree, feature importance, or validation result tables after run_analysis succeeds.
