fix(V0.2): 二轮评审 6 项 —— BUILD_ID 格式 / 菜单与详情精简 / 拖动重做 / 键盘统一方案

1. BUILD_ID 改为 yyyyMMddHHmmss (去掉中间点), 仍 UTC+8
2. 任务 ⋯ 菜单去掉顶部任务名标题
3. 任务详情去掉底部「拷贝到其他项目」「删除任务」按钮 (⋯ 菜单已有)
4+6. 键盘遮挡统一方案 (重点设计 §7.2):
   - index.html 加 interactive-widget=resizes-content
   - App 级 useKeyboardInsetWatcher 写 --kb-inset (visualViewport+window 双源)
   - 底部弹层统一 .kb-safe 类 (安全区+20px+键盘插入量, dvh 收缩+内部滚动)
   - TaskDetail/UserPicker/CopyTaskPopup/信息块弹层全部迁移, 删除 per-component hook
   - 信息块 textarea 补 focus scrollIntoView 兜底
5. 拖动方案重做 (重点设计 §7.1):
   - 新 useColumnDrag: Pointer Events + setPointerCapture, 长按400ms原位抬起,
     elementFromPoint 高亮目标列, 边缘 rAF 自动横滚; 移除手指跟随浮层(任务名)
   - 列表行长按 500ms → 「移动到列」ActionSheet (不做自由拖动)
   - 移除「拖到卡片转子任务」误触路径, 统一走详情页层级区
   - 删除旧 useLongPressDrag
