账号与团队：SQLite 云端空间（个人 / 团队共享 + 自动同步）

- 服务端（Gin + modernc.org/sqlite，data/opsxapi.db WAL）：
  - users/tokens/teams/team_members/workspaces 表；注册登录（加盐哈希 + Bearer 令牌）
  - /api：auth register/login/logout、me（用户+团队+空间）、teams CRUD/邀请成员、workspaces 读写（20MB 上限，成员鉴权）
- 前端：
  - account.ts 客户端 + store 账号态：登录/注册/登出/团队/空间切换
  - 顶栏账号区：未登录「登录」按钮；登录后用户胶囊（头像+空间名+已同步/同步中/失败）+ 空间切换菜单 + ⋯（立即同步/团队管理/退出）
  - 空间模型：本地（localStorage）与云端（SQLite）隔离，切云端空空间自动播种本地数据；云端改动 1.5s 去抖自动同步；切回本地恢复快照
  - 登录/注册弹窗 + 团队管理弹窗（建团队、邮箱邀请）；vite 代理 /api；docs 新增「账号与团队」页
- 验证：curl E2E（注册/冲突 409/错误密码 401/团队共享写/越权 401）+ 浏览器全链路（注册→播种上云 17KB→云端编辑自动同步→本地快照隔离）
