feat(ui): 查标、概览改为左右布局；招标文件、投标文件左右切换

- 查标结果页、概览和读标页一样：左边内容随页面滚动，右边原文贴住视口，去掉原文侧边抽屉
- DocStage：查标右侧招标文件、投标文件横向排开，当前的占满，另一份露出 80px
  （文件名移到露出的一侧、纸边、带方向箭头的竖排标签，截断处淡入页面底色，悬停时探出一点）；
  点露出的一条或另一边的出处就滑过去，两边各自记着页和高亮
- 查标：进页面翻到第一条问题的出处，J / K 时原文跟着翻，优先留在正在看的一边；
  左边变窄后问题行改单列，出处放在说明下面，快捷键提示收成「快捷键」
- 概览：关键日期和采购包合成一张卡放到最上面，项目要点在下
- 原文查看器：直接打开到某页时会并发两次渲染、叠出镜像乱字，改为后一次等前一次停下

 - 2026-11-04：项目基本信息修改和分包选择（FR-M2-03、04，`docs/architecture/project-info-plan.md`，PI1–PI7 全部按建议确认）。新增「概览」标签页（项目要点可改、带出处、可恢复 AI 值；采购包；关键日期）和选包页（手工调整、一键「不分包」）；清单默认只列通用 + 所投的包；检查记下当时用的截止时间、限价、所投的包、法律体系，报告按它写，之后改了信息查标页提示重新检查。样本里分包识别对的只有 S10（S06 把分项认成 5 个包，S01、S08 单包写了包号），改进分包抽取记进读标专项。
 - 2026-11-05：补遗追加（FR-M2-10，`docs/architecture/addendum-plan.md`，AD1–AD6 全部按建议确认）。招标文件解析后可以追加补遗 / 澄清（单独解析、扣 1 次），新条目标「补遗 N」进正式清单、清单回到草稿；同一种日期时间不同的旧条目标「已被补遗 N 更新」，项目字段的新值在概览「采用 / 不采用」，采用截止时间时日期条目一起确认，没确认前查标用旧值、检查预览提示。补遗不改项目名称、编号、采购人等（更正公告标题会被抽成项目名称）。真实模型对虚构更正公告抽得对；还没有真实补遗样本。
 - 2026-11-05：读标、查标全流程走查（浏览器从注册走到导出报告）。修了走查发现的问题：原生下拉换成按规范 §7.21 的 `SelectBox`（Reka UI，和搜索框同高，长选项不再挤压签名）；关键日期去重；报告页致命数改读项目的实时值；★ 只是「重要」的文件清单项也挂到 ★ 规则上；检查范围文案过期；报告出处不重复文件名（模板 2026.11-v3）。查标结果页按原型补齐：本次处理的留在原位、J / K / O / 1 / 2 / 3 / X / U 键盘、「提示」批量确认、「判断有误？」反馈、覆盖范围默认收起、导出报告入口；项目头改为「就绪 / 未就绪」，致命数挂在查标标签上。
+- 2026-11-05：查标结果页、概览改成和读标页一样的左右布局（左边内容，右边原文贴住视口），去掉原文侧边抽屉。查标右侧招标文件、投标文件左右切换（`components/DocStage.vue`）：当前的占满，另一份露出一窄条（文件名、纸边、带方向箭头的标签，截断处淡入底色），点它或点另一边的出处就滑过去，两边各自记着页和高亮，J / K 时原文跟着翻。概览把关键日期和采购包合成一张卡放到最上面。修了原文查看器直接打开到某页时重复渲染出镜像乱字的问题。内容区四角改为直角（设计规范 §5.3 同步）。
 - 下一步：国动真实投标文件（用户晚些提供，到时先读标、请用户看清单，再查标一次；请用户按公司真实证书录资质库；有更正公告一起要）；其余可做：第 6 步前端补齐（键盘操作、批量处理、判断有误反馈、日期选择器的日历弹层、概览页的检查记录和文件卡）、M6 剩下的 P0（额度流水、套餐开通、数据删除、运营后台）。
