SARIMA 预测

确认时间频率和季节周期，检查数据长度能否覆盖足够周期。执行季节模型与时间验证，报告参数、误差、预测区间和季节模式；数据不足时不要强行拟合。

Use get_schema to identify the time column, target column, seasonal frequency, and source table.
Use query_data only to verify sorted frequency, missing periods, and enough seasonal cycles.
Use run_analysis with analysis_name="Time_Series_SARIMA" for the actual forecast computation.
Use generate_chart on forecast or seasonal diagnostic result tables after run_analysis succeeds.
