qualify_local_types and qualify_workspace_types were two ~55-line
recursive Type rewriters identical in every arm (Con skip-guards for
already-dotted and primitive names; Fn/Var/Forall recursion) except
the bare-name decision: the local form rewrites iff the name is in
local_types; the workspace form leaves names own to the module bare
and otherwise searches module_types for the defining module.
Factor the recursion into one rewrite_type_cons that takes the bare-
name decision as a `&dyn Fn(&str) -> Option<String>` (Some = rewrite to
this qualified name, None = leave bare). The two public functions are
now thin wrappers passing their respective closure. Recursion order
and Con-arm check order are preserved exactly; cross-module
qualification tests green.
