一、采样间隔/频率显示不一致（用户报告 1ms vs 1000us、100us 0ns） * FormatDurationCompound 改为「先量化到整数皮秒、再整数分解」， 彻底消除同一数值因浮点噪声落到不同单位/留下零尾数的问题； 秒级分支与亚秒分支共用 totalPs 方案，次级进位/单位升级集中在一处。 * FormatFrequency 的单位选择改为按「舍入后的显示值」判定（999.9999999Hz 与 1000Hz 均为 1.000kHz），并做向下校正避免 0.001kHz。 二、选区截取面板 * 提示文本改为用户指定原文「启用双光标模式以进行选区截取」。 * EdgePanelWidth 计入该提示的实际文本宽度；绘制改用 UiTextClipped 不再省略。 * viewHeight 补回漏减的 bottomPad，修掉条目区与按钮之间的空白。 三、未展开的信号条目栏悬停不再变成手型光标。 四、开启「显示布局边界」后 GX 标签可正常拖拽排序 * 抽出 PaintLaneReorderOverlay（吸附槽位 + 被拖轮廓），贴图与整幅重绘共用。 * 整幅重绘在 LANE_REORDER 时按 LaneDragOffset 逐格平移重画（被拖网格最后画）， 修掉调试模式下不跟随鼠标、无吸附提示、只能盲拖的问题。 五、信号右键新增「移动到…」二级菜单（位于「仅显示该信号」之上） * 条目为「分组 N（组名）」，当前组打勾；无标题行；底部「新建分组」。 * MenuItem::submenuMaxRows + PopupMenu 独立子菜单滚动（滚动条、滚轮、视口命中过滤）， IsScrollable 计入子菜单可滚状态。 * 数据层 DataSet::MoveSignalToGroup/MoveSignal 让时间轴随信号搬运 （独占则移动、共享则复制）；TabConfig::RemapAfterSignalMove 改写引用而非先删后插。 * Application::MoveSignalCore 统一入口，保证派生计算暂停、引用修正、选中迁移与同步一致。 六、信号列表支持按住拖拽排序（组内重排 / 跨组移动） * 4px 阈值进入拖拽；条目脱离原位跟随鼠标（阴影 + 强调色描边 + 插入指示线）。 * 其它信号行/分组行按插入位置做避让位移动画（RowRect 统一叠加插值位移， 宿主 kScrollTimerId 驱动 AdvanceSignalDragAnimation）。 * 数据层 DataSet::MoveSignal 支持任意位置；TabConfig::RemapAfterSignalReorder 线性重映射。 * 拖拽中禁用组名悬浮；双击改名与 InvalidateRows 均正确终止拖拽态。 验证：删 .o 全量重编译零 error / 零 warning；产物 873,984 B（< 1MB 预警阈值）。 本轮未使用鼠标/键盘/屏幕，未运行任何 GUI 探针，仅编译验证 + 源码级核对。

// PlotView 实现分片 —— 几何：浮动面板布局、图例徽标几何、"自由标记"的取值/标签/探测。
|
||
//
|
||
// 本分片只包含 `PlotView` 的**成员函数定义**（从 `PlotViewPaint.cpp` 机械搬移，行为与搬移前逐字节一致）。
|
||
//
|
||
// 为什么要独立出来：
|
||
// * 这些函数**被高频询问**（`TopPanelAtPoint` / `SyncPanelOrder` / `QueryCursor` / 绘制各算一遍，
|
||
// `EdgePanelLayoutFor` 一度有 19 个调用点），属于"几何"而不是"绘制"；
|
||
// * 与绘制混在一个文件里时，改动布局会连带触碰 9 千行的绘制文件，回归面被放大。
|
||
//
|
||
// ⚠️ 硬约束：
|
||
// 1. `EdgePanelLayoutFor` / `EdgePanelWidth` 会被鼠标移动的高频路径调用 ⇒ **不得**逐条查询采样值，
|
||
// 枚举列缺省只允许查 `SignalEnumText::Empty()`（O(1)）。
|
||
// 2. 布局结果必须"绘制与命中同源"：绘制侧不得自行反推列边界。
|
||
// 3. 面板几何键（`PanelSlotKey` 等）留在 `PlotViewPaint.cpp`（属于缓存键，不属于几何）。
