- Preserve multi-line doc comments (/// and /** */) instead of collapsing
- Skip duplicate create method when already emitted as factory constructor
- Skip fields/constructor/fromMap/toMap for abstract interface classes
- Parse nested enums/structs/classes and resolve dotted type refs (SHA2.Variant → SHA2Variant)
- Make constructorParameters nullable to distinguish no-init from parameterless-init
- Deduplicate methods in Swift and Kotlin glue generators
