refactor(op): remove automatic Path assignment

[j2rong4cn]

Description / 描述

• api不再返回文件对象的Path和Id，对于客户端来说没什么用处，徒增数据传输量
• 移除op.List的自动设置Path，Path和Id只在驱动内使用，不应由op.List设置Path
• cnb_releases：将 Addition 结构体中的 RootPath 字段为 RootID
  当List方法加载二级目录时，若使用的是Id，应对使用driver.RootID

Pull request overview

This PR refactors path handling by removing automatic path assignment from the op layer and delegating this responsibility to individual driver implementations. The changes simplify the architecture by making path management explicit at the driver level.

• Removed automatic path assignment logic from internal/op/fs.go and internal/op/archive.go
• Removed Id and Path fields from API response structures (ObjResp)
• Updated all storage drivers to explicitly set the Path field when creating objects

正确的，很久之前就想吐槽这件事了。

另外我个人建议直接删除model.Obj的GetPath和GetID方法，新增model.ObjWithPath（不一定叫这个，我觉得不好听）接口实现Obj、GetPath和GetID，op层和上层使用model.Obj交互，和驱动使用model.ObjWithPath交互，有效避免在开发上层模块时误把GetPath的返回结果当全局路径使用的问题。

建议直接删除model.Obj的GetPath和GetID方法

要加很多类型断言，还是算了，改的地方太多

要加类型断言不就说明确实有更上层的模块使用了GetPath，不就说明上层的模块是有bug的

另外pr搞吧
