so Git picks the right credential from the multi-account store
- PROJECT_GUIDE: document ShowOverlay and the retired-config table with the
reason each key existed without effect
- README: point releases, clone URL and CLI examples at the unified binary
and the spearzificial repository
- TODO_CHECKLIST: add the release pipeline, dead config, ShowOverlay and
