feat(argus-semantics): finish quantitative semantics

Browse source 
The Boolean semantics are still incomplete. The decision to keep the
computations separate stays, as using the quantitative semantics for
Boolean values (while sound) interpolates in weird places.
May revisit this decision in the future
