Getting Started gains three parts: installing with go install, from a
clone or as the Docker image; a crontab line for a daily root scan,
with where its stderr and failures go; and how to read the two reports,
why a row is a candidate rather than proof, and how to check a pair
with cmp before removing anything. The usage block names --help, and
the text below it --workers and -x.
The install line uses @main, not @latest: @latest resolves to the
v0.0.1 tag, which predates the database.
