// 之前：删除了关键转换，破坏前端显示
return { ...track, name: track.title, cover, quality: track.bitrate ?? 0 };

// 之后：保持正确的数据格式
return {
  ...track,
  name: track.title,
  cover,
  size: track.size,           // 字节数，供 formatFileSize 处理
  duration: track.duration * 1000,  // 转为毫秒
  quality: track.bitrate ?? 0,
};

// 之前：类型不安全
export const getArtistNames = (artists: any): string[] => {
  // ...
}

// 之后：明确类型定义
type Artist = string | { name?: string };
export const getArtistNames = (artists: Artist | Artist[]): string[] => {
  // ...
}

// utils/paths.ts - 单一来源
export const getCoverDir = (): string => {
  return getLocalDataPaths().coverDir;

// ipc-file.ts & LocalMusicService.ts - 复用
import { getCoverDir } from "../utils/paths";
