v1.10.3 — clean up patch log progress-bar spam

Fixed

• Patch logs showed huge blocks of repeated text from progress-bar redraws (apt percentage updates, needrestart's process/candidate scan bars, dpkg's "Reading database..." counter). These tools use carriage returns (\r) to redraw the same terminal line in place; the SSH output reader only split on newlines, so every redraw frame got crammed onto one giant line instead of collapsing to the final state.
• Carriage-return redraws are now collapsed to their last frame, matching what you'd actually see watching the terminal live.
