Use cmdline apps like gdb interactively

Hi @mattdwells, I get what you’re going for here, and it makes a lot of sense. Moving Codex toward a more asynchronous, event-driven setup where one instance can juggle multiple live sessions and reprioritize in real time feels like a pretty natural direction, especially for things like terminal workflows and interactive debugging. Appreciate you taking the time to lay this out, the details are really helpful. I can’t share a timeline right now, but this is great context on what could make the workflow a lot more capable, and I’ll pass it along internally. -Sunny
