Disable Answer with AI feature by default

The “Answer with AI” feature that’s on by default in Brave Search needs to be an opt-in feature, not opt-out, not only because many (probably most) people don’t want it to begin with, but because of how it causes the non-AI results to be shifted down the page while trying to click on things or scroll through results, causing unnecessary frustration to either wait for the AI to finish its simulated typing out of an answer (instead of just instantly showing whatever it’s going to say, and not trying to pretend it’s actually a person typing anything) or to go to the settings and turn it off, then have to refresh the page to remove the already-generated AI result.
