"scout" regex escaping

[whatisaphone]

Behavior differs from vscode here.

Baseline:

• Hit ctrl+f to make sure regex is enabled (click the .* icon), then back out with esc
• Type a(b in a new file, select it with the mouse, and hit ctrl+f
• When vscode copies the text to the find box, it escapes it, resulting in a\(b

Cursorless:

• Type a(b in a new file, and say scout three tokens air
• The text is copied to the find box without escaping: a(b, and the find box will be covered with an error saying the regex is invalid
