+- **dev SPA Ctrl+V 粘贴上传反馈改成可预览 chip**:`web/static/dev.html` `uploadFiles()` 成功时返回 `/v1/files/upload` 的 `saved[]` 元数据,粘贴文件后 `#chat-hint` 显示"已粘贴" + `.art-chip` 文件 chip + "可在右侧文件处查看",不再 4s 自动消失,下一次发送时由原有"发送中…"状态覆盖。chip 点击复用 `openFilePreview`;若主文件预览框已打开,改开新增的 `#mini-preview-modal` 小预览窗(支持 image/video/pdf/text/md,其它格式给下载兜底),避免覆盖用户当前正在看的主预览。`DESIGN.md` 不动(纯 dev SPA 交互);`RUN.md` 不动(运行方式无变化)。
 - **dev SPA 三栏支持右文件栏折叠 + 左右分隔线拖拽调宽**:`web/static/dev.html` 主布局从 3 列 grid 改为 5 列 grid(任务栏 / 左 splitter / 对话栏 / 右 splitter / 文件栏),新增 `#split-left` / `#split-right` 两条 6px 拖拽分隔线,拖动时分别调整 `--left-pane-width` / `--right-pane-width` 并持久化到 localStorage(`zcbot.left-width` / `zcbot.right-width`)。右侧文件栏新增 `#pane-toggle-right`,折叠态复用左栏 rail 范式:列宽 40px,只保留展开按钮,状态持久化到 `zcbot.right-collapsed`;手机端继续走三 tab 单列,隐藏折叠按钮和 splitter,避免与移动端导航冲突。`DESIGN.md` 不动(纯 dev SPA 布局交互);`RUN.md` 不动(运行方式无变化)。
 - **dev SPA 右侧文件列表长名称 hover 显示全路径**:`web/static/dev.html` 在右 pane 文件行 `.file-row .name` 和"选入…"源文件列表 `.sp-row .sp-name` 上补 `title`,内容取 `e.rel || e.name`,保留现有 ellipsis 截断视觉,鼠标悬停可看完整相对路径/名称。`DESIGN.md` 不动(无架构/心智模型变化);`RUN.md` 不动(运行方式无变化)。
 - **dev SPA 左侧滚动条只覆盖 task 列表**:`web/static/dev.html` 左 pane 改成 flex column,顶部 4 行 pane-head(任务标题/新建/搜索筛选/排序)固定不参与滚动;`#task-list` 与 `#task-sentinel` 包进 `#task-scroll`,并把 IntersectionObserver root 从 `#pane-left` 改到 `#task-scroll`,保证无限滚动仍按列表区域触发。`DESIGN.md` 不动(无架构/心智模型变化);`RUN.md` 不动(运行方式无变化)。
