网格右键菜单: - 菜单顺序改为: 网格 N / Y 轴最大值 / Y 轴最小值 / 选区 Y 轴自适应 / --分隔线-- / Y 轴自适应 / 时间轴自适应 / 全部自适应 （恢复自适应移到分隔线以下、时间轴自适应上方） - Y 轴最大值/最小值改为菜单内联输入框：点击就地编辑、回车提交，菜单不关闭， 处理方式与拾色器的 RGB 内联编辑一致；提交后按真实夹取结果回写菜单显示值， 并同步刷新自适应项的文案/对勾/可用状态 - 新增"选区 Y 轴自适应"：只按当前显示时间段内的数据做幅值自适应 （时间单调时二分定位区间，非单调时全扫并按区间过滤） 大文件加载: - 加载改为工作线程执行（解析 + 按列重组），主线程抽送消息并播放过渡动画 （旋转弧线 + 进度条 + 文件名 + 百分比 + 按 Esc 取消），界面不再整块卡死 - 加载完成后主线程只做一次 O(1) 的移动入队，不会产生可见卡顿 - 新增 DataModel::BuildDataFile / DataSet::AddPreparedFile：不依赖 DataSet， 因此可以安全地在线程上运行 内存与解析效率: - CsvTable 由"行优先二维数组"改为"列优先"：百万行文件原先会产生上百万次独立堆分配 （每行还有 vector 控制块与容量对齐开销），现在每列一整块连续内存 - 解析改为流式分块读取（4MB），不再把整个文件读入内存，也没有体积上限 （原先超过 512MB 直接拒绝）；实测 51MB 文件峰值内存约 126MB（数据本身 113MB） - BuildDataFile 直接把整列移动进 SignalData（零拷贝），不再逐元素复制 - TryParseDouble 增加十进制快速路径：ucrt strtod 实测约 335ns/次，手写路径约 13ns （快 25 倍）；非十进制写法（十六进制浮点、inf/nan、带尾部杂字符）原样交回 strtod， 输入接受语义完全不变（实测与 strtod 的差异不超过 1 ULP） → 640MB 测试文件加载时间由约 40s 降到 2s 以内 交互流畅性: - 拖拽（平移/框选/拖动信号）期间关闭波形抗锯齿并压缩顶点预算（2 像素一列包络）， 松开后立即恢复全质量绘制；实测 BIG_DATA 10 信号全显示的帧耗时由 105~168ms 降到 75~90ms（其中折线绘制 55ms→23ms） - 折线包络抽稀改为"列边界单调推进"的二分，避免每列在全区间二分造成缓存缺失 - 未对波形构建引入多线程：构建已由几何键缓存消除，且拖拽降级后仅约 1~2ms/帧， 并行化收益不足以抵消线程与同步的复杂度（加载路径的多线程收益明确，故只在该处引入） 图标: - 窗口类与 WM_SETICON 原先使用系统默认图标 IDI_APPLICATION，导致标题栏、 任务栏与 Alt+Tab 缩略图都显示成通用应用图标；改为按 SM_CXICON/SM_CXSMICON 从应用的 IDI_APP_ICON 资源加载（多尺寸 ICO 会挑选最接近的一帧） 其他: - PopupMenu 新增 EDIT 项类型（菜单内联输入框）与 UpdateItemValue/UpdateItemLabel
