I've set `lexical-binding` to `nil` in all Emacs Lisp files to suppress
the warnings introduced in Emacs 31 requiring all elisp files to have a
`lexical-binding` comment.
This retains the default behavior of dynamic binding when no
`lexical-binding` comment is present. With it set to `t` across the
board, various things break, and fixing those is a task for another day.
Caddy can now format Caddyfiles with the "caddy fmt" command, so we use
reformatter to create a format-on-save mode for Caddyfiles.
Also there's no need for the weird whitespace-mode workaround, as we now
use tab indentation in Caddyfiles, since that's what "caddy fmt"
produces.
When whitespace-mode is enabled, single-line copilot completions makes
the cursor look like it's at the end of the completion rather than in
it's real position.
Issue with gifs showing the behavior is here:

For the most part I should be able to live without whitespace-mode in
day to day use, and improvements to the highlight-indent-guides setup
should help.
And worst case, whitespace-mode can always be toggled easily enough.
