I would argue that this is not a matching delimiter pair at all. It is the scope type string which we have no spoken form for at the moment.

Haven't reviewed everything, but left a few comments

This is really interesting

"if the file is over 30MB or over 300k lines, we consider it to be a very large file and proceed to turn off very many features, including tokenization, word wrapping, indent guides, anything that would consume additional memory, etc."
microsoft/vscode#32118 (comment)

That means that Cursorless can never encounter a file with over three hundred thousand lines. I just did a test with the surrounding pair regex on a file with just below three hundred thousand lines and that clocked in at 274ms. I would say that is a bit on the high side so we might want to do some windowing, but we definitely don't need to be as careful as we was before. Doing it at tens of thousand lines at the time probably is fine.
