Subject: [PATCH] fix: use backslash as path separator on Windows (#2684)

I noticed that when running `/status` on Windows, I saw something like:

```
Path: ~/src\codex
```

so now it should be:

```
Path: ~\src\codex
```

Admittedly, `~` is understood by PowerShell but not on Windows, in
general, but it's much less verbose than `%USERPROFILE%`.
