New modules/user/dotfiles.sh behind a menu question ('Clone personal
dotfiles?', default no) and --dotfiles=yes|no flag.
Does a --bare clone of yuri/fedora-dots into ~/.cfg.git, checks the repo
out into $HOME with status.showUntrackedFiles=no, and handles an empty
repo gracefully (configures the alias, skips checkout). Existing
~/.cfg.git is left untouched (idempotent).
Fix proven in the harness: the module originally used a plain git clone,
which creates a working copy and breaks the git-dir alias — the same
failure YuKu hit manually; --bare is required.
Dispatch runs the dotfiles module before DE/TWM so configs are in place
when sessions are installed.
