fix(display): reset the screen after degraded out-of-operation lines

A plain line printed outside any operation lands below the tracked
block, so the block is no longer directly above the cursor. Reset the
screen so the next operation repaints a fresh block instead of moving
the cursor over rows that shifted — the same reason unsuspend resets
after buildkit output.
