feat: set terminal background color

relates to #529
relates to #322
relates to #497

Windors terminal and Visual Studio Code do not work well with inversted
ANSI sequences. This weak allows users to override the Tranparency to
the terminal background color removing black elements in their prompt.

Ideally we remove this once they are on par with other terminals, but
that could take a while.
