feat(privesc): drop classic sudo via AssumeInstalled

base-devel hard-depends on the sudo package, so without help, pacman
refuses to remove it. The Arch-native fix is pacman.conf's
AssumeInstalled directive: tell pacman to pretend a virtual
sudo=99.0 is installed and base-devel's dep is satisfied without
actually pulling sudo in.

- etc/pacman.conf: AssumeInstalled = sudo=99.0
- bootstrap.sh: after 'just init' (which writes the AssumeInstalled
  line and installs sudo-rs), Rns the leftover sudo package so a
  fresh install ends up with sudo-rs only.

Also reformat bootstrap.sh and the etc deploy script with the
project's shfmt style (-i 2 -ci -s).
