 - **会话管理** — 多会话切换、重命名、删除
 - **本地持久化** — Room 数据库，App 杀死重启后自动恢复
 - **Material3 动态取色** — Android 12+ 自动适配主题色
 - **Markdown 渲染** — AI 回复中的粗体、代码块、链接等
 - **连接状态指示** — 实时显示 WebSocket 连接状态
 - **消息复制、时间戳、长文本折叠** — 便捷的消息交互
 ## 技术栈
 - **语言**: Kotlin 2.2
 - **UI**: Jetpack Compose + Material3
 - **WebSocket**: OkHttp 4.12
 - **数据库**: Room 2.7 (KSP)
 - **构建**: Gradle 9.4 + AGP 9.2
 - **最低支持**: API 28 (Android 9)
