// TDD Test: Verify struct field shorthand doesn't break type conversion
// Bug: E0308: Using field shorthand `User { name }` when `name: &str` but field is `String`
// Root Cause: Codegen uses field shorthand even when type conversion is needed
// Fix: Don't use field shorthand when parameter type != field type
