//! 音乐下载模块(musicdl 桥接)。
//!
//! 架构:Vue 前端 → Tauri 命令 → [MusicManager] → stdio JSON-Lines → `bridge.py`
//! → musicdl(纯 Python 聚合下载器)。
//!
//! 目录布局({app_data_dir}/music/):
//! - `bridge.py`:桥接脚本(include_str! 内置,运行时写出)
//! - `runtime/python/`:便携 Pythonpython.org embeddable,含 pip
//! - `runtime/get-pip.py`pip 引导脚本(下载后删除)
//! - `runtime/*.zip`:下载过程中的临时安装包(完成后删除)
//! - `outputs/`:默认音乐下载目录
//!
//! 子模块:
//! - [`runtime`]Python 运行时探测与便携版安装
//! - [`bridge`]:桥接进程生命周期(spawn / JSON 协议 / ping / 停止)
//! - [`commands`]Tauri 命令层
