/*! 🗄️ MapBox - キー値ストレージBox
*
* ## 📝
* Box
* JavaScript MapPython dictC# Dictionaryと同等機能
*
*
* ## 🛠
* - `set(key, value)` -
* - `get(key)` -
* - `has(key)` -
* - `remove(key)` -
* - `clear()` -
* - `keys()` -
* - `values()` -
* - `size()` -
* - `isEmpty()` -
*
* ## 💡 使
* ```nyash
* local map, result
* map = new MapBox()
*
* // データ設定
* map.set("name", "Alice")
* map.set("age", 25)
* map.set("active", true)
*
* // データ取得
* result = map.get("name") // "Alice"
* print("User: " + result)
*
* // 存在確認
* if (map.has("email")) {
* print("Email: " + map.get("email"))
* } else {
* print("No email registered")
* }
* ```
*
* ## 🎮 -
* ```nyash
* static box GameConfig {
* init { settings, scores }
*
* main() {
* me.settings = new MapBox()
* me.scores = new MapBox()
*
* // 設定初期化
* me.settings.set("difficulty", "normal")
* me.settings.set("sound", true)
* me.settings.set("graphics", "high")
*
* // スコア記録
* me.scores.set("level1", 850)
* me.scores.set("level2", 1200)
* me.scores.set("level3", 950)
*
* me.displayConfig()
* }
*
* displayConfig() {
* print("=== Game Settings ===")
* print("Difficulty: " + me.settings.get("difficulty"))
* print("Sound: " + me.settings.get("sound").toString())
* print("Total scores: " + me.scores.size().toString())
* }
* }
* ```
*
* ## 🔍
* ```nyash
* static box APICache {
* init { cache, ttl_map }
*
* main() {
* me.cache = new MapBox()
* me.ttl_map = new MapBox()
* }
*
* getData(url) {
* // キャッシュ確認
* if (me.cache.has(url)) {
* return me.cache.get(url)
* }
*
* // APIから取得
* local data
* data = fetchFromAPI(url)
*
* // キャッシュに保存
* me.cache.set(url, data)
* return data
* }
* }
* ```
*
* ##
* -
* - (Arc<Mutex>使)
* - 使
* - "Key not found"
