Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! 此拉取请求旨在全面提升音乐缓存服务的智能性和可靠性。通过引入音质优先级管理和独立的缓存元数据文件，系统现在能够更精确地管理和选择缓存的音乐文件，确保用户始终获得最佳音质体验。同时，MD5验证机制得到了显著增强，利用元数据缓存避免了重复计算，从而提高了缓存验证的效率和准确性。 Highlights

这个空的 catch 块会静默地吞噬错误，这可能导致潜在问题难以调试。建议捕获异常并记录一条警告日志，以便追踪可能发生的异常，例如当 getFilePath 抛出错误时。

在下载完成后，计算 MD5 和写入元数据可能会阻塞 cacheMusic 函数返回，特别是对于大文件。由于元数据写入不是关键路径，可以考虑将其作为非阻塞的“即发即忘”任务在后台执行。这样可以更快地返回文件路径，提升用户体验。同时，在后台任务中也应该妥善处理异常。
// Fire-and-forget metadata writing
(async () => {
try {
const finalStats = await stat(filePath);
const finalMD5 = await this.calculateMD5(filePath);
await this.writeMeta(filePath, finalMD5, finalStats.size);
} catch (e) {
cacheLog.warn(`[MusicCache] Failed to write metadata for ${filePath}:`, e);
}
})();

应该不影响合并(( 不小心把env传上来了 现在回学校了要等下周再改
