docs/scripts(kaisa): add doctor verify mode and HDMI readiness checks

Add a more detailed --verify flow to capture Jack/ELD/subdevices, route per sink, and collect kernel error windows. Improve --fix with readiness gating, retries, and connected-only selection; document single-monitor pcm mapping behavior and ignore local logs/artifacts.
