工况预测类（处理二维倒序数据，返回一维列表，仅保留各内嵌列表最新记录）
|
||
功能：根据输入的带时间序列的工况数据，推导每个监测点（point_id）的下一阶段工况
|
||
特性：
|
||
1. 输入为二维列表，每个内嵌列表对应一个point_id，且为倒序排列（最新记录在索引0）
|
||
2. 输出为一维列表，仅保留每个内嵌列表的最新记录，新增工况推导结果字段
|
||
3. 无需切换工况时，next_workinfo返回当前工况名称；需要切换时返回目标工况名称
|
||
4. 时间计算仅按日期（天）维度，忽略时分秒
|
||
5. 支持冬休场景：当前工况为冬休时，以冬休前上一个有效工况作为切换判断依据
