feat(miniprogram): 访客模式 + 长辈模式 + MCP 自动化脚本

访客模式：
- 未登录用户可见首页（轮播图+健康资讯+登录引导）和"我的"页面
- 健康和消息 tab 显示 GuestGuard 登录拦截
- 登录页增加"暂不登录，先看看"跳过入口
- 401 拦截器增加 hasToken 检查，避免访客被重定向到登录页
- 退出登录后 reLaunch 到首页而非登录页

长辈模式：
- 新增 stores/ui.ts 管理显示模式（标准/长辈）
- 长辈模式放大字体 ×1.3、间距 ×1.2、按钮加大
- "我的 → 账号 → 长辈模式"切换页
- 设置持久化到 Storage

修复：
- Health/Messages 页面 Hooks 顺序违规（条件 return 在 hooks 之间）
  导致访客模式下页面白屏，所有 hooks 移到条件判断之前

工程：
- scripts/mpsync.sh/ps1 自动清理残留 DevTools 进程
- project.config.json 默认关闭域名校验
