数据层与视图配置解耦：新增 DataSet（多文件只读数据层）与 TabConfig（每标签页独立配置），
以 SignalRef{fileIndex,signalIndex} 标识全局信号，替换原有单文件 SignalSet。
- 标签页：新增 TabBar 组件，支持新建/切换/关闭标签页；每页独立保存信号勾选、
颜色/线宽/显示方式、网格划分、视图范围与时间光标，互不影响。
- 网格收敛：可见性变更统一经 TabConfig 的 Set*Visible 接口并同步重算网格，
取消勾选后对应的空网格立即回收（修复此前留下空轨道的问题）。
- 多文件分组：左侧面板改为「文件分组 + 信号」树形列表，分组可折叠、可整组勾选，
分组复选框支持全选/部分/未选三态；新加载文件的信号默认未勾选，由用户自行选择。
- 来源标识：信号行、样式编辑区标题、波形图例与光标读数在跨文件时标注来源文件名。
- 交互补充：面板滚动条支持点击跳转与拖拽，切换标签页自动滚动到已选信号。
- 工具栏精简为「打开 CSV/适应视图/放大/缩小/合并网格/每信号一格/全选信号/清空勾选」，
按钮宽度改为按实际文本像素测量；打开对话框支持多选文件，拖放支持批量载入。
- 新增 TestData/[2].CSV 作为跨文件对比测试数据。
