//! 插件清单解析
//!
//! ## PHP 对齐
//!
//! 对齐 PHP `think\Addons::getInfo()` 的行为：
//!
//! ```php
//! // vendor/zzstudio/think-addons/src/Addons.php:85-110
//! final public function getInfo(): array
//! {
//!     // 1. 先读缓存
//!     $info = Config::get($this->addon_info, []);
//!     if (empty($info)) {
//!         // 2. 合并子类 $info 属性与 info.ini 文件
//!         $info = $this->info;
//!         $info_file = $this->addon_path . 'info.ini';
//!         if (is_file($info_file)) {
//!             $info = array_merge($info, parse_ini_file($info_file, true, INI_SCANNER_TYPED));
//!         }
//!     }
//!     // 3. 自动注入 url 字段
//!     $_info['url'] = addons_url();
//!     Config::set($info, $this->addon_info);
//!     return $info;
//! }
//! ```
//!
//! ## Plugin.php 清单字段
//!
//! 对齐 PHP 插件入口文件的 `$info` 数组：
//!
//! | 字段 | 类型 | 说明 |
//! |------|------|------|
//! | `name` | string | 插件标识（与目录名一致） |
//! | `title` | string | 插件标题 |
//! | `identifier` | string | 插件唯一标识符 |
//! | `icon` | string | 图标路径 |
//! | `author` | string | 作者 |
//! | `version` | string | 版本号 |
//! | `admin` | string | 后台管理 URL |
//! | `status` | int | 状态（1=启用，0=禁用） |
