No-AI desktop path: PyQt bot wired to the page

- templates/bot_runner.py (new, no Qt): runs the bot as a child process
  (unbuffered, UTF-8), tails its output, keeps raw lines in bot_raw.log,
  and turns lines into step/log/status events. Step markers and friendly
  rules use specific substrings, first match wins; unmatched error lines
  are always shown, other unmatched lines hidden. Dry run:
  python dashboard/bot_runner.py prints the events the page would get.
- bridge.py: delegates to bot_runner, one run at a time, restores the
  saved dark mode on every page load (fixes sample-data mode in PyQt),
  adds load_latest_report / download_report slots the page calls.
- SKILL.md: skip the stack question for a PyQt project; desktop wiring
  steps from the bot's real output; verify steps for the host.
- tests: assert-based self-check for the line logic and run loop; Seam 1
  run replay (status dot, Run button, steps, log) and wired-page mode;
  fixture b-pyqt-bot and its Seam 2 eval (all 14 checks pass).
