* ♻️ 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 --------- Co-authored-by: webjoin111 <455457521@qq.com> Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com>
