- 文档：recruiter_architecture §14 弹窗清单与 §6 常量更新；CLAUDE.md 补充登录后弹窗说明；
  新增 plan/README.md、plan/chat_page_tab_navigation.md。

+**Known post-login popups** — all must be auto-dismissed or automation will hang:
+- **Governance notice** (`dialog-uninstall-extension`) — appears every login; handled by `dismissGovernanceNoticeDialog(page)` in `index.mjs`, called after login in both `launchBrowserAndNavigateToChat` and `startBossAutoBrowse`. Confirm button is `div.confirm-btn` (a `<div>` styled with a background image, not a `<button>`). See `plan/recruiter_architecture.md §14.1` and `examples/BOSS直聘-治理公告*.html`.
