GRU 预测

仅在样本量和序列长度足够时使用。确认窗口、特征和预测期，严格按时间划分训练验证，避免泄漏，报告基线对比、误差和不确定性；小数据优先建议传统时序模型。

Use get_schema to identify the time column, target column, feature columns, and source table.
Use query_data only to verify sorted sequence length, missingness, and whether the sample size is sufficient.
Use run_analysis with analysis_name="Time_Series_GRU" for the actual model computation.
Use generate_chart on forecast or validation result tables after run_analysis succeeds.
