#129) ### Summary - In `TyCollector::visit_ty` (`src/printer.rs`), after successful closure instance traversal, record closure `Ty` metadata in `types`. - Update integration golden files (`tests/integration/programs/*.smir.json.expected`) to match emitted closure `FunType` metadata. - Keep `Makefile` integration path as `TESTDIR=tests/integration/programs` to keep closure fixture output paths stable. ### Context In the closure arm of `TyCollector::visit_ty`, the code resolved and visited the closure instance but returned without inserting the closure `Ty` into `types`. Other type families were inserted; closures were the exception. This made downstream closure type lookup incomplete (notably for kmir proof paths that consume exported type metadata). Recording closure `Ty` closes that gap. Related split: static/vtable alloc fallback changes were moved out to [stable-mir-json#131](#131) so this PR stays focused on closure metadata. Dependency context: this PR is depended on by [mir-semantics#957](runtimeverification/mir-semantics#957).
