优化思考模式AI回复的UI显示，支持<think>标签解析
新增功能： 1. 创建消息解析工具 message-parser.ts - 解析 <think> 标签，提取思考过程 - 分离思考内容和实际回复 2. 创建思考过程展示组件 thinking-block.tsx - 可折叠/展开的思考过程区域 - 参考 GPT-5 和 Claude 网页版设计 - 默认折叠，点击展开查看详细思考过程 3. 修改聊天消息组件 chat-message.tsx - 集成思考过程解析和展示 - 思考过程单独显示在顶部 - 实际回复正常显示在下方 4. 新增样式 thinking-block.css - 契合当前淡绿色(#a4e2ad)配色方案 - 渐变背景和流畅动画效果 - 灯泡图标标识思考过程 - 完整的响应式设计 UI效果： - 思考过程：淡绿色渐变背景，可折叠区域 - 实际回复：正常Markdown渲染 - 交互流畅：展开/折叠动画平滑 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
