feat: Add MatcherApp. and CasesOnApp.refineThrough (#2882) 
these are compagnions to `MatcherApp.addArg` and `CasesOnApp.addArg`
when one only has an
expression (which may not be a type) to transform, but not a concret
values.

This is a prerequisite for guessing lexicographic order (#2874). Keeping
this on a separate PR because it’s sizable, and has a clear independent
specification.
