Describe the bug / provide steps to reproduce it

Expected Behavior

When using zed --wait or zed -w with folders, the CLI should wait for all files opened from that folder to be closed before returning control to the terminal, similar to how it works with individual files.

Actual Behavior

While the -w flag works correctly with individual files, when used with folders, it doesn't wait for files to be closed and returns control immediately.

Steps to Reproduce

1. Open terminal
2. Run zed -w /path/to/folder
3. Observe that the CLI returns control immediately instead of waiting for files in the folder to be closed
4. Compare with working behavior: zed -w /path/to/specific/file.txt (works as expected)

Use Case

This is particularly problematic for automation scripts (e.g., NixOS update scripts) where waiting for folder content review is necessary before proceeding.

Additional Context

The --wait functionality works as documented for individual files but seems to not extend to folder operations, which limits its usefulness in automation scripts where folder monitoring is needed.

To be explicit, you'd like zed -w foldername to block and wait until the workspace window associated with that directory is closed?

I would simply expect a different behavior than simply returning control, but I believe the details of the implementation should be left as a decision for those contributing to Zed, so I can't say much, other than my preference, that being have it wait for the window related to the terminal that Zed was called from to be closed.
