As a convenience for the user, this makes it easy to see at a glance how long
the current build has already been running.

The progress bar for the overall build currently shows only a percentage and
a bar, with no running time — while each individual running-task line below
it already carries an elapsed-time value. The patch adds a Timer widget to
the bar, reusing knotty's existing time formatting so it matches the rest of
the UI.
