Terminal/tab suffix shows codex" (stray quote in process/app name)

Re-opening ticket as original fix did not solve.

@etraut-openai @ianmcvann Yeah I'm still seeing the exact same issue as I reported it. I'm also on the latest version. It doesn't appear like the fix actually worked - should we re-open this ticket instead of creating a new one? https://github.com/user-attachments/assets/5f66d3a8-4dfe-4ca2-975a-5817608e8cc4
