…casts) into forall-sort

Brings in coord-e#114 (Rust expressions as thrust::predicate bodies,
instantiated per generic arguments), coord-e#275 (newer PCSat in CI), coord-e#276, coord-e#277
and coord-e#278 on top of forall-sort.

Resolution:
- A predicate call whose instance resolves goes through
  Analyzer::predicate_with_args, so a Rust-body predicate is defined once
  per instantiation and a raw SMT-LIB2 predicate keeps its single
  definition. A call that does not resolve (it still depends on the
  owner's type parameters) keeps the forall predicate.
- predicate_with_args takes the calling function as owner, since
  forall-sort translates type parameters relative to it; an instance
  whose arguments mention type parameters is keyed by that owner too.
- UserDefinedPredDef keeps both the new body enum and the ForallPred
  dependency set. A formula body contributes its ForallPred atoms
  directly and its calls to other user-defined predicates as edges of
  the dependency graph; a raw body is still scanned by name.
- The refinement clause builder records the value-variable origin only
  when the value term is a variable, as the singleton case substitutes
  a default term.
