macOS Darwin 25.5.0 arm64 arm

What issue are you seeing?

Using the Image Gen skill, previews are rendered OK in chat but the thread cannot find the image on the file system if needed so falls back to API (if available) or something else.

Result:
- `$imagegen` preview rendered in chat.
- No file appeared under `$HOME/.codex/**/generated_images`.
- No recent `.png`, `.jpg`, or `.webp` appeared anywhere under `$HOME/.codex`.

So the built-in image generation display works, but the generated asset is not being written where Codex can access/copy/upload it.

It all worked fine before upgrading to this version.

What steps can reproduce the bug?

Use the Image Gen skill to create an image and ask to copy that image to another location.
Also, the image no longer appears in $HOME/.codex/**/generated_images.

What is the expected behavior?

The image should appear in $HOME/.codex/**/generated_images and the thread should be able to access it.
