What issue are you seeing?

Almost every command gives output like this, about trying to read .keychain, I have no idea why.

• Ran cargo fmt

What steps can reproduce the bug?

Just ask it to run some git or cargo commands in a repo.
I'll also note that I've had this issue since I started using codex a few months ago, so it's not a newly introduced bug.

What is the expected behavior?
