[Feature] Press ESC to stop generating

[perholmes]

Easily my #1 feature request would be to be able to stop generating with a keyboard shortcut. Currently, it's always a mouse operation, which means trying to hit a tiny moving box with the mouse, and a constant tool change.

ChatGPT's web interface can stop generating by pressing ESC, and this is a motor-memory you use countless of times every day.

ESC should just stop all generating currently in progress.
