main: 增加工具调用支持及相关功能集成

- 添加多个工具卡片组件，包括 LsResultCard、BashResultCard、FileReadResultCard 和 ToolCallCard
- 更新 ChatView 消息处理逻辑，支持工具消息的解析与展示
- 实现工具调用与结果处理机制，完善工具消息的归一化及合并逻辑
- 优化消息界面，新增工具调用列表与对应的样式调整
- 更新工具调用相关功能的状态管理与交互逻辑

+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## 项目概述
+
+ARS（Agent Runtime Server）前端 Demo，一个基于 Vue 3 + Vite 的 SPA，为智能体运行时后端提供会话管理和消息展示界面。与 `ars-backend` 配合使用。
+
+## 常用命令
+
+```bash
+# 安装依赖
+npm install
+
+# 启动开发服务器
+npm run dev
+
+# 生产构建
+npm run build
+
+# 运行所有测试
+npm test
+
+# 运行单个测试文件
+npx vitest tests/chat-view.spec.js
+
+# 运行匹配模式的测试
+npx vitest -t "message.delta"
+```
+
+## 环境配置
+
+- `VITE_API_BASE`: 后端 API 基址，默认 `http://localhost:8000/api`
+
+## 架构概览
+
+### 技术栈
+- **框架**: Vue 3 (Composition API + `<script setup>`)
+- **UI 库**: Element Plus
+- **路由**: Vue Router 4
+- **HTTP**: Axios
+- **Markdown**: markdown-it + mermaid
+- **测试**: Vitest + Vue Test Utils + jsdom
+
+### 目录结构
+```

+└── composables/
+    └── useTheme.js         # 主题切换逻辑
+tests/                   # Vitest 测试文件
+```
+
+### 核心数据流
+
+1. **认证**: JWT token 存储在 `localStorage` (`ars-token`)
+2. **会话管理**: 当前会话 ID 存储在 `localStorage` (`ars-current-session`)
+3. **实时消息**: 通过 SSE (Server-Sent Events) 接收增量消息
+4. **主题**: 支持 light/dark/system，存储在 `localStorage` (`ars-theme`)
+
+### ChatView 消息处理逻辑
+
+ChatView 是最复杂的组件，处理以下消息类型：
+- `user.prompt`: 用户输入
+- `agent.message`: Agent 最终回复
+- `message.delta`: 流式增量内容（打字机效果）
+- `run.status`: 运行状态（RUNNING/DONE/FAILED）
+- `error`: 系统错误
+
+关键机制：
+- `dedupe_key` 去重防止重复消息
+- `run_id` 将同一运行的 delta 和 final message 关联
+- `finalizedRunIds` 标记已完成的运行，忽略后续 delta
+- 打字机效果通过 `typingStates` Map 管理
+
+### 测试模式
+
+测试使用 jsdom 环境，需要 mock：
+- `axios` 的 HTTP 请求
+- `EventSource` 的 SSE 连接
+- `mermaid` 渲染
+- `window.scrollTo`
+
+## 样式约定
+
+- 使用 CSS 变量定义主题色（见 `style.css`）
+- 组件使用 `<style scoped>`
+- 响应式断点：900px/960px
