- ConfigRegistry.RemovePlugin(name)：删除 defs 中 plugin.<name>.* 配置项定义
  （该插件 RegisterDef 注册的全部配置项）+ DROP 插件配置表 config_<name>
  （含用户设置值）；ListPlugins 基于 config_% 表枚举，卸载后插件配置区
  在 WebUI/Settings API 中完全消失
- Registry.RemovePlugin 在 RemoveDisabledPlugin 基础上追加 RemovePlugin 调用；
  语义与 onRemove 回调（清数据文件）互补：删除 = 数据文件 + 配置 + 注册全清，
  disable/重载不清配置
