* ♻️ refactor(UI): 重构UI渲染服务为组件化分层架构

♻️ **架构重构**
- UI渲染服务重构为组件化分层架构
- 解耦主题管理、HTML生成、截图功能

✨ **新增功能**
- `zhenxun.ui` 统一入口，提供 `render`、`markdown`、`vstack` 等API
- `RenderableComponent` 基类和渲染协议抽象
- 新增主题管理器和截图引擎模块

⚙️ **配置优化**
- UI配置迁移至 `superuser/ui_manager.py`
- 新增"重载UI主题"管理指令

🔧 **性能改进**
- 优化渲染缓存，支持组件级透明缓存
- 所有UI组件适配新渲染流程

* 🚨 auto fix by pre-commit hooks
