Is there a way to preserve toolbox PWD upon exit?
I.e.: This is the behavior today:
```
$ pwd
/home/user

$ toolbox enter

⬢ [toolbox:41] $ cd bin

⬢ [toolbox:41] $ pwd
/home/user/bin

⬢ [toolbox:41] $ logout

$ pwd
/home/user
```

**Describe the solution you'd like**
I would like a way to preserve toolbox PWD upon exit:
```
$ pwd
/home/user

$ toolbox enter

⬢ [toolbox:41] $ cd bin

⬢ [toolbox:41] $ pwd
/home/user/bin

⬢ [toolbox:41] $ logout

$ pwd
/home/user/bin
```

Start by tracing the toolbox enter and logout command handling and how the host shell's current directory is passed into and out of the toolbox. Reproduce the documented /home/user to /home/user/bin example, then determine how the host directory can reflect the directory reached inside the toolbox. Done means exiting after cd bin leaves the host shell in /home/user/bin.
