v0.56.2

Changed

• The Jobs panel colours each job's state: blue for running, amber for
  queued or waiting, green for done, red for failed, grey for paused or
  cancelled. The word stays beside the dot, so colour is never the only
  signal, and each colour is checked for contrast in both themes.

Fixed

• S did nothing on a burst reached with the arrow keys in the photo
  view. It opened the stack in the Library behind the photo, but the
  filmstrip kept showing one tile. The frames now appear in the filmstrip,
  and the status line says how many there are.
