Consider adding to <project>-worktree.sh a setup step

[drabaioli]

This adds to ~/.bashrc a line like
[[ -f "$HOME/Code/cdd/tools/cdd-worktree.sh" ]] && source "$HOME/Code/cdd/tools/cdd-worktree.sh"

Should it be something like ./<project>-worktree.sh self-install? so self-install as an argument? or something similar?
