v0.4.1

Fixed

• Detached rows no longer flicker white on updates. The detached-row dimming
  decoration was invalidated wholesale on every tree refresh, so a Claude status
  update — which never changes attach-state — flashed every dimmed row's label to
  full strength for a frame before re-dimming. The decoration now fires only for
  rows whose attach-state actually changed, and stays silent on status-only
  refreshes.
• Corrected the Explorer context menu label "Open in Detach Session" → "Open in
  dtach Session".
