[PATCH] knotty: show elapsed time on the task progress bar

[-- Attachment #1.1: Type: text/plain, Size: 464 bytes --]

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.

Thanks,
WXbet

Subject: [PATCH] knotty: show elapsed time on the task progress bar

The progress bar for the overall build shows a percentage and a bar but no
elapsed time, even though the individual running-task lines below it each
show one.

Add a Timer widget to the bar. The time formatting in
TerminalFilter.elapsed() is hoisted to a module-level bb_elapsed() helper and
reused by a small progressbar.Timer subclass, so the bar prints the same
"%dh%dm%ds" style as the rest of the UI.
