When using @ to reference a file in Codex, file suggestions stop appearing if the file path is too long.

What steps can reproduce the bug?

1. Open Codex App.
2. Work in a project or folder that contains files under a long nested path.
3. In the prompt box, type @ and start typing the file name or path.
4. Observe that no file suggestion appears for the file with the long path.

What is the expected behavior?

No suggestion appears, so the file cannot be selected through the @ reference UI.

Additional information

Shorter paths appear to work normally. The issue seems related to path length rather than the file itself.
