Reconcile §Source wording with the lean knowledge index

The BCQuality filter now emits a lean index whose per-article description is a
one-line hint rather than the full verbatim Description. Update the six domain
skills' §Source to say the index carries a one-line description hint (keywords,
title, and a one-line description) instead of the full description. The
worklist selection predicate is unchanged: keywords drive selection and the
agent opens worklisted articles in full for their rule bodies.
