loadbearer v0.5.1

• The --soak phase now runs inside the TUI. On an interactive loadbearer run --soak, the sustained-load phase gets its own live screen — a progress
  gauge, current throughput, current clock, retained-vs-peak-so-far, and a
  throughput sparkline that grows a mark per sample — instead of running as a
  plain stderr line after the TUI closed. q skips the soak and keeps the
  graded result; a soak that produced at least a few samples is still embedded
  in the result file. The results screen gains a one-line SOAK summary.
