This seems to do what you want for the changes. The timestamp is
automatically added when you make changes. It does not propagate
timestamps up though, so if you change a subheading the timestamp there
is updated, but the one in the parent for example. also, this will
update every headline.
You may need to add another (add-hook 'org-mode-hook (lambda ()
(add-to-list 'after-change-functions 'update-last-edited))) kind of line
to enable this in all org-files, the code below might be buffer local.
#+BEGIN_SRC emacs-lisp
(defun update-last-edited (beg end length)
(when
(and
(not (org-before-first-heading-p))
(org-get-heading))
(org-entry-put nil "LAST-EDITED" (format-time-string "[%Y-%m-%d %a
%H:%M:%S]"))))
(add-to-list 'after-change-functions 'update-last-edited)
#+END_SRC
