Add an option to suppress comments in code review prompts for certain words

[azyu]

Background

I'm using prompts with strong rules (e.g., only check for underflow and overflow concerns, and leave 'LGTM' if there's nothing wrong). Why did I write this prompt? Unfortunately, prompts like “Please do not add any comments” didn't work well.

But in general, if there's nothing wrong with code, end up with as many comments saying 'LGTM' as there are changed files. This is more like noise.

It would be nice to have option to not register that comment if the response contains a specific phrase.
