/**
 * 阿里云百炼 Qwen-TTS Provider（同步模式）
 *
 * 接口限制参考:
 *   - Qwen-TTS (multimodal-generation): 单次 20,000 字符（同步/流式）
 *   - CosyVoice (SpeechSynthesizer): 单次 20,000 字符（同步/流式）
 *   - 传统长文本合成: 80,000 字符（建议 40,000 以内）
 *   - 传统基础合成: 300 字符（已弃用）
 *
 * 调用方式:
 *   - 同步非流式: POST → 直接返回音频 URL
 *   - SSE 流式: 加 X-DashScope-SSE: enable header
 *   - ⚠️ 不支持 X-DashScope-Async 异步模式
 *
 * 当前策略: 使用同步模式 + 1000 字符分段，每段快速返回音频 URL
 *
 * 文档: https://help.aliyun.com/zh/model-studio/qwen-tts
