fix(guide): count new findings in the markdown summary, as its heading does

The markdown report's summary line counted every finding while its heading and
the severity counts beside it counted only new ones, so a fully baselined run
read "20 findings ({error: 0, warning: 0, info: 0})" above "## Findings (0)".
The summary now counts new findings and notes how many are baselined.

Also: loading-flag-not-reset rendered its flag as `SettingsState`loading``, a
missing `.` that produced two adjacent code spans. It now reads
`SettingsState.loading`.
