+/**
+ * Claude-4.5-Sonnet适配器（便捷封装）
+ * 
+ * 通过CloseAI代理访问Anthropic Claude-4.5-Sonnet模型
+ * 
+ * 模型特点：
+ * - 准确率：93%
+ * - 速度：中等
+ * - 成本：¥0.021/1K tokens
+ * - 适用场景：第三方仲裁、结构化输出、高质量文本生成
+ * 
+ * 使用场景：
+ * - 双模型对比筛选（DeepSeek vs GPT-5）
+ * - 三模型共识仲裁（DeepSeek + GPT-5 + Claude）
+ * - 作为独立裁判解决冲突决策
+ * 
+ * 使用示例：
+ * ```typescript
+ * import { ClaudeAdapter } from '@/common/llm/adapters';
+ * 
+ * const claude = new ClaudeAdapter();
+ * const response = await claude.chat([
+ *   { role: 'user', content: '作为第三方仲裁，请判断文献是否应该纳入...' }
+ * ]);
+ * ```
+ * 
+ * 参考文档：docs/02-通用能力层/01-LLM大模型网关/03-CloseAI集成指南.md
