- 「实验性功能」二级菜单新增带勾选的「均值滤波」：开启后为本网格每条信号叠加绘制
一条 N 点滑动平均曲线，算法与「边沿计数（中心轴）」的中心平均值曲线**完全一致**
（同一实现 ComputeMovingAverage），配色同样由信号色派生为高对比度颜色、透明度一致。
- 新增均值滤波浮动面板：标题栏可拖拽、✕ 关闭，面板内列出被处理的信号名、
「均值点数 N」内联编辑行，以及底部的「构建为新信号」按钮（悬停高亮 + 手型光标）。
- 「构建为新信号」：把滤波后的曲线作为新信号插入，命名为「<原信号名称> (N点均值)」，
归属到原信号所属组的原信号位置**下方**，成为独立的新信号；其所在网格也移动到
原信号网格的下方。合并网格时一次按钮为该网格内每条可见信号各构建一条。
为此新增 DataSet::InsertDerivedSignal / TabConfig::RemapAfterSignalInsert /
TabConfig::MoveLaneOfSignalBelow / TabConfig::RenameLanes（插入位置之后的信号引用
与可见性列同步重映射）。
- 光标交互与「边沿计数（中心轴）」同构：光标处标注均值滤波曲线的取值
与双光标增量，文案为「值（均值滤波）」/「值（+增量 均值滤波）」；
两条派生曲线的取值胶囊已抽成同一段绘制逻辑。
- 浮动面板种类由 bool centerAxis 改为 EdgePanelKind{COUNT,CENTER,MEAN}，
布局/宽度/命中测试/绘制统一走同一套几何。
- 以 VERY_BIG_DATA.CSV 验证：曲线预览、N 编辑、双光标取值标注、
单信号与合并网格两种情况下的新信号命名与插入位置均正确。
