This commit refactors the way record types are computed within the optimizer. Previously, the optimizer would often reuse the existing `NodeMetrics` for records, which could lead to stale or polymorphic types. The changes introduce a new function, `compute_record_type`, which explicitly recalculates the `StaticType` for a `Record` node based on the concrete types of its child fields. This ensures that after optimizations like inlining and folding, record types are as concrete as possible, eliminating unresolved `TypeVars`. Additionally, the `folder.rs` module is updated to recompute the `RecordLayout` when creating constant record values, further improving type accuracy. Two new tests are added to verify that inlined records, including those with multiple fields, correctly result in concrete types.
