Fixed

Both Engines

• Keyboard controls now work reliably — P, R, S/Q, W keys previously had
  no effect unless pressed during a narrow window between page-loop iterations.
  Root cause: the listener thread stored keys in _key but the main loop
  only called get_key() once per page (every 10–30 s), so most keypresses
  were missed. Fix: P and S/Q now set threading.Event flags (_pause_event,
  _stop_event) directly inside the listener thread, so they take effect
  immediately — even when the main loop is blocked in time.sleep() or a
  tqdm iteration. R clears _pause_event immediately. W remains stored
  in _key and is consumed by the main loop to print stats.
  InputController gains is_paused() and is_stopped() helper methods;
  both scrapers updated to poll these instead of a local paused variable.
• Dead-website retry: 0 → 1 — profile/crawl fetches now retry once on
  ReadTimeout and general connection errors. ConnectTimeout (TCP-level
  failure — host is unreachable) still returns ("", 0) immediately with
  zero retries, so truly dead sites never stall the run.

Added

Documentation

• docs/ folder added to the repository root for visual assets.
  Contains docs/README.md with step-by-step instructions for recording
  terminal-demo.gif (asciinema) and capturing excel-preview.png.
  docs/.gitkeep ensures Git tracks the empty folder.
• README Output Preview — placeholder text replaced with an HTML comment
  block that is ready to uncomment once assets are placed in docs/.
• README Project Structure — updated to show the docs/ folder.
