重构：CodeMirror 架构优化

核心优化：
- 新增统一导出避免多实例问题
- 语言加载器从动态改为静态导入
- 使用 Compartment 实现主题/语言动态切换

依赖清理：
- 移除废弃的 @codemirror/highlight
- 移除不再使用的 @codemirror/legacy-modes

组件优化：
- CodeEditor 添加内容更新防抖
- 改进亮色主题样式
- 移除不必要的编辑器重建逻辑

构建配置：
- 简化 Vite manualChunks 配置
- 优化依赖预加载列表

文档清理：
- 删除过期的代码审查文档
- 更新版本号 0.3.0 → 0.3.2
