Problem

When multiple Codex sessions in the same project share the same first user message, the codex resume --all list preview shows that first
message for all of them, making it hard to distinguish sessions.

What steps can reproduce the bug?

Steps to Reproduce

1. Start multiple Codex sessions in the same project with identical first user messages.
2. Run codex resume --all or codex resume .
3. Observe that previews are identical because they show the first user message.

What is the expected behavior?
