Add better screen reader support

[ai]

It will be nice if screen reader users have this flow:

1. Move focus to textarea
2. Input some config
3. Press some key
4. If there is a warning server will read it
5. What server send back result, browser should read the results
6. They can press some button to move cursor back to form

Maybe we should add a hotkey and remove Skip to button. But for hotkey we need to add a notice (like on OKLCH picker) about what they need to press.
