[VSCode extension] Add option to hold off on applying patches until I accept them

What feature would you like to see?

Basically, please just copy Copilot. I know that _usually_ it will give me the option to display a diff and undo the changes, but very frequently and with no discernible reason it stops doing that. It would be so much more helpful if it just had the same behaviour as copilot where suggested edits are displayed in a diff-like style inside the editor with the option to accept or decline. This can be configurable for people who don't like it.
