Cut weak interest matches and add the rating-driven affinity signal (step 2)

Browse Source 
An interest matches an article only when it is in the top three by z and
z >= 1.0, so the Matches line, the stored rows and the weights agree. The
new bounded affinity signal blends each matched interest's rating-derived
weight, gated on attributable ratings like feed affinity.
