feat(skills): show description as subtext under the skill name

Lives in the name track as a second truncated line (max-w 36rem,
title attr for the full text) — no track, no header, no slot in the
responsive arithmetic. Both lines fit the fixed 48px row, so the
virtualizer contract is untouched; rows without a description center
the name.
