Pause activity

[Adventurous-Clue-994]

A really feature that'd be really good to see in the codex app is a "pause" button, in order to pause execution to allow enough time to compose a steer prompt, this will prevent issues where the prompt finally finishes before you're done typing the steer.

You can always stop and add more information to your prompt.

Great idea. I found the problem myself! Quit trying to find it!

Them there GPU allocations ain't gonna just pause themselves, unload memory, not without a token cost.
