feat: add deepseek-harness workbench plugin and console diagnosis API

- console: GET /api/workflows/{id}, /runs/{run_id}, /runs/{run_id}/diagnosis
  (journal trace + sanitized bounded log tails, workflow/run pairing enforced)
- workbench/: dsh 宿主插件（7 个工作流工具、中文系统提示词、失败监控器、
  本机回环桥接服务）+ 侧边栏面板客户端包（sidebar.footer.action 与
  shell.overlay 追加插槽）+ 降级独立面板 + 一键启动脚本
- adapters/browser: 收敛 looks_like_login_url 到共享层，修复
  jd_main_image_collector 对 gyxx_flow.accounts 的越层导入
- tests: 新端点覆盖；replay_policy 断言对齐已迁移的 catalog（repeatable）
