//! Worker 构造器绑定：Box 分配构造器（不占 `BuiltinWorld` P 字段、不新增
|
||||
//! `BuiltinId`、不占 `BuiltinDirtySet` 脏位）加 `track_leaked_object` 加填原型
|
||||
//! 占位加全局槽，全槽 `lookup_position` 幂等守卫。
|
||||
//!
|
||||
//! 与 `bind_iterator_global` 同型：构造器经 `Box::into_raw` 登记 world 释放
|
||||
//! 登记表（session 收尾统一释放），全局 `Worker` 槽经 `bind_constructor!` 原位
|

//! 安装（既有槽更新槽值、无槽新开）。
