1) 菜单滚动时最上方的「所属网格」标题不再跟着滚走
- 根因：上一轮只实现了“尾部固定区”（最后一个分隔线 + 「新建网格」钉在底部），
而滚动区是从条目 0 开始的，于是标题也被一起滚掉。
- 修法：BuildLayout 新增 m_scrollFirst（= 前导 HEADER / HEADER_ACTION 的个数），
滚动区收敛为半开区间 [m_scrollFirst, m_pinnedIndex)：
· 前导标题从菜单顶向下固定排（不参与滚动）；
· 滚动区条目受 m_scrollOffset 影响；
· 尾部固定区从菜单底向上对齐。
- 配套：Paint 的裁剪与“跳过不可见条目”范围、ItemAtPoint 的“必须落在滚动视口内”判定、
EnsureItemVisible 的下界全部改用该区间；新增 ScrollRegion(first, last) 供查询/测试。
2) 菜单长度上限改为「最多 10 条网格」并加滚动条
- MenuLayoutConstraint 新增 maxScrollRows（滚动区最多显示的标准行数；与 maxHeight
同时给出时取更严格者）；OpenLaneMenu 传 10（kLaneMenuVisibleRows），
另保留 maxHeight = max(180, 客户区高 × 0.8) 作为矮窗口的硬上限。
- 新增滚动条：轨道贴滚动条目区右内侧（不盖住标题与底部固定项），滑块高度按视口/内容比
（下限 22 逻辑像素）；滚动区条目宽度让出 kScrollBarWidth + kScrollBarGap，
文本与对勾不会压在滑块上。
- 滚动条可拖拽：按下滑块 → 拖动（只改偏移、不更新悬停）；点击轨道空白 → 滑块中心移过去；
松开结束拖拽且不下发命令、菜单保持打开。新增 ScrollOffsetForThumbTop 反算偏移。
- ⚠️ BuildLayout 绝不能复位 m_scrollBarDragging：拖拽时每帧都会 RebuildLayout()，
在那里清零会让拖拽“拖一下就脱手”（该状态只在 Open / Close 里复位）。
3) 网格滚动联动改为动态过渡（旧实现直接把视界瞬移过去，过于僵硬）
- PlotView::ScrollLaneIntoView 只负责启动平滑动画：与信号列表的“滚动到目标信号”同源
（ease-out cubic；时长 clamp(距离×0.35ms, 130, 300)），新增
m_laneScrollAnimActive/From/To/StartMs/DurationMs。
- 宿主 16ms 定时器（kScrollTimerId）调用 AdvanceLaneScrollAnimation() 逐帧推进，
与信号面板动画共用同一条定时器；Render 的“需要保持定时重绘”判定加入
LaneScrollAnimationActive()。
- 每帧 ClampLaneScroll() + BuildLaneVisuals()（网格滚动量参与场景/图层指纹与各网格 rect）；
结束时精确落到目标。已完整可见的网格仍然不启动动画。
- ⚠️ 用户自己滚动网格（滚轮 / 拖滚动条）会 CancelLaneScrollAnimation()，避免与动画抢滚动位置。
验证（全部离屏执行：窗口 SW_HIDE + 只注入合成消息 + 进程与线程 BELOW_NORMAL，
不移动真实光标、不抢焦点、不截屏）：
- .preflight/check 扩到 95 项，95/95 通过；新增断言：
· 菜单顶部标题在滚动时不动（Y 坐标不变）、滚动视口高度恰为 10 × 行高；
· 滚动条轨道/滑块存在、随滚动移动、按住滑块拖到底（菜单不关、不下发命令、末条目入视口）、
滚轮回到顶部；
· ScrollLaneIntoView 不瞬移（刚触发时几乎未动）、中间帧单调递进、收尾精确到位、
已可见时不启动动画、滚轮/手动滚动会取消动画。
- A/B：回退三处（标题固定 / 10 行上限 / 滚动动画）⇒ 10 项如实失败；恢复后 95/95。
- make release / make debug 零警告。
文档：Documents/agent_mem.md 新增 §9.39、§11.2 第 104–107 条与变更日志一行。
