本轮实现功能： 1. 多用户隔离：每个用户独立 config.json + graph.db 2. TUI 登录页 + 旧版自动迁移（core/migrate.py） 3. Admin/User 角色体系（core/embedded_db.py） 4. Web 后台管理 API（userinfo + admin CRUD） 5. Web 设置页用户管理区（仅 admin 可见） 6. TUI 侧栏配置区权限同步（非 admin 隐藏 Web 服务设置） 7. Web 服务打包为独立二进制（trulymem-web） 8. 双入口 PyInstaller 构建脚本（TUI + Web） 9. 活动记录器（core/activity_recorder.py） 10. 静态页面模板（登录/设置/首次引导）
