The `SubstitutionMap::new_inner()` method provides a more robust way to create nested substitution maps, ensuring that only global substitutions are inherited. This prevents potential issues with overlapping local and upvalue addresses in nested scopes, such as during lambda inlining. This change also includes: - A new `try_fold_record` method in `folder.rs` to optimize record literals into constant values. - Updates to `inliner.rs` to recognize `Value::Record` for inlining. - Various test cases to verify record optimization and constant folding.
