Include the settings for diff-so-fancy somehow :)

Not sure how it will work if you don't install it.. but it would be nice to include this.. https://github.com/so-fancy/diff-so-fancy

Start by inspecting the repository's existing shell and dotfile configuration, then review the linked diff-so-fancy project to understand which settings could be included. Define how the settings should behave when diff-so-fancy is not installed; the work is done when the configuration is integrated without breaking the existing setup.
