Pure JS's util module for well-known iOS network tools

/**
 * 当前运行平台名称（脚本平台优先，模块系统次之）。
 * Current runtime platform name (script platform first, module system second).
 *
 * 识别顺序:
 * Detection order:
 * 1) `$task` -> Quantumult X
 * 2) `$loon` -> Loon
 * 3) `$rocket` -> Shadowrocket
 * 4) `Egern` -> Egern
 * 5) `$environment["surge-version"]` -> Surge
 * 6) `$environment["stash-version"]` -> Stash
 * 7) `Cloudflare` -> Worker
 * 8) `process.versions.node` -> Node.js
 * 9) 默认回落 -> undefined
 *    default fallback -> undefined
 *
 * 说明:
 * Notes:
 * - 使用 `'key' in globalThis`，避免 `Object.keys` 对不可枚举全局变量漏检。
 * - Use `'key' in globalThis` to avoid missing non-enumerable globals with `Object.keys`.
 *
 * @type {("Quantumult X" | "Loon" | "Shadowrocket" | "Egern" | "Surge" | "Stash" | "Worker" | "Node.js" | undefined)}
