## ObjectPool — 通用对象池（Autoload: ObjectPool）
|
||
## 权威来源：implementation_plan.md §2.1 Layer-0
|
||
##
|
||
## 使用约定：
|
||
## 1. 被池化对象必须实现 reset() 方法 （签名：func reset() -> void）
|
||
## 2. 取出：pool.acquire() → 返回对象（内部已调 reset()）
|
||
## 3. 归还：pool.release(obj)
|
||
extends Node
|
||
|
||
## 创建一个指定工厂和容量的对象池
