Owned registration metadata used by file-backed authoring and reloads. 文件创作与热刷新使用的拥有所有权注册元数据。

Compile-time declarations keep RegistrationInfo as a small static value. Runtime-authored values must not borrow from a process-global intern pool, so this type owns every reloadable field and can be dropped with the snapshot that produced it. 编译期声明继续使用小型静态 RegistrationInfo；运行时创作值不能借用进程级 intern 池，因此这里拥有所有可重载字段，并随快照一起释放。
