 Default config goes to `%APPDATA%\mpa-skill\config.json`. Does not modify Zotero database or Obsidian settings. Add `-WhatIf` to preview; run `Test-MpaEnvironment.ps1` to check your setup.
+If the config file already exists, initialization stops and preserves it. Pass a new `-ConfigPath` to create another configuration.

 默认配置写入 `%APPDATA%\mpa-skill\config.json`，不修改 Zotero 数据库或 Obsidian 设置。预览操作加 `-WhatIf`；检查环境用 `Test-MpaEnvironment.ps1`。
+若配置文件已存在，初始化会停止并保留原文件；要创建另一套配置，请指定新的 `-ConfigPath`。
