DeepSeek V4.1 Flash fe72afc83c 绘图交互完善 + 稠密区域拖拽性能修复(VERY_BIG_DATA 2ms/大格不再卡顿)
一、功能修正
- 修复「光标数据点在上下视界外不绘制」的问题,并让上下越界与左右越界一样用三角表示:
  新增 `DataMarker` / `PaintDataMarker()`,统一处理「可视区内画圆点、越界则钉在网格边上
  画三角指示方向」的四向情形(左/右/上/下)。光标取值与中心轴取值都改走这一套,
  因此纵向被裁掉的数据点不再消失。
- 「边沿计数(中心轴)」的中心平均值曲线改为**跟随原信号的样式**:
  与原始信号同色但更透明,线宽同样跟随(lineWidth + 0.6,下限 1.4),
  原信号改颜色/线宽/透明度后曲线同步变化(曲线参与场景指纹,样式变化即失效重绘)。
  光标显示中心值时的胶囊也改用**原始信号颜色**(一一对应),并**始终按线段模式**着色,
  不再使用光标色。
- 「拆分当前网格」在可点击时追加尾缀「(N个信号)」(N = 该网格内信号数),
  只有 1 条信号(不可点击)时不加尾缀。

二、新增:左侧信号筛选框
- 信号列表上方新增「筛选信号」输入框:空内容时显示灰色占位提示,单击进入编辑,
  点击别处或回车结束编辑;列表内容随输入**实时**变化。
- 支持 `*` 通配符(`*` 等价于"任意字符",因此 `*` 单独出现等价于不过滤),忽略大小写。
- 筛选结果**仍以组为单位**,组默认展开,只显示匹配的信号;组内无匹配信号时整组不显示。
- 复用统一的 `TextEdit` 编辑模型,因此光标/选区/Ctrl+A/C/X/V 等行为与其它输入框一致。

三、性能:修复 VERY_BIG_DATA.CSV 在 2ms/大格密集区域拖拽卡顿
以「显示全部 5 条信号 + 时间轴缩放到 2ms 一大格」为场景逐段打点定位后修复:
- **主因:稠密包络的锯齿描边光栅化**。抽稀时每列产生 min/max 两个顶点交替的锯齿,
  2000+ 条近乎满幅的斜线段在 GDI+ 抗锯齿下要光栅化几十万像素(实测每网格 14ms,
  5 网格约 70ms/帧)。
  改为**包络带一次填充**:逐列记录上/下包络,收段时拼成「上包络正向 + 下包络反向」的
  闭合多边形,用一条 `GraphicsPath` + `FillPath` 绘制(显式 `FillModeWinding`,
  自交包络不会挖洞)。基准测试(1224 列):14.26ms → **1.69ms(约 8.4 倍)**,
  且**保留抗锯齿**、静态帧与拖拽帧完全一致(不是"交互降级")。
  逐像素对比确认观感等价(墨量覆盖率 90.8% vs 91.3%)。
  包络带同时用于静态绘制与 MOVE_SIGNAL 的拖拽虚影。
- **大面积不透明填充改走 GDI**:`UiFillRect` 在面积 ≥ 20000px² 且颜色不透明时使用
  `GetHDC + FillRect`(GDI+ FillRectangle 约 2.2ns/像素,整窗背景 1.7M 像素要 0.9ms、
  面板背景 1.9ms)。半透明填充仍走 GDI+(GDI 不做 alpha 混色);小面积仍走 GDI+
  (避免 GetHDC 固定开销)。顺序安全:GetHDC 会先刷入已排队的 GDI+ 内容。
- **`UiTextWidth` 不再触发 GDI+ 批次刷新**:改为复用 `UiMeasureTextWidth`
  (`GetDC(nullptr)`),`UiEllipsize` 逐字符回退时的十几次刷新被完全消除。

实测(125% 缩放、1725x996、5 信号、2ms 一大格):
  绘图区绘制 47~87ms → **3.6~4.5ms**;整帧最大 196.8ms → **约 17~21ms(≈50~60fps)**,
  与空闲帧基本持平,即"拖拽与不拖拽一样流畅"。

验证(VERY_BIG_DATA.CSV;面板行坐标因新增筛选框整体下移,复选框客户区 (61,250) 起、行距 33):
- 筛选框:输入 `B` 后只剩「编码器B相」「电流钳采集(ABSx10)」,组仍展开;清空即恢复。
- 拆分:合并 3 条信号后右键显示「拆分当前网格(3个信号)」;单信号网格该项置灰无尾缀。
- 光标/中心轴:竖线光标取值与中心值胶囊均按四向越界正确显示三角/圆点。
- 稠密区域:5 信号全选 + 缩放到 2ms 一大格,左键拖拽信号、左键平移、中键平移均流畅;
  渲染观感与修改前等价(叠图对比)。
- make clean && make all 无警告无错误。
