structuredClone turns boxed BigInt values into plain objects

Description

The React Native structuredClone polyfill handles boxed Boolean, Number, and String values but omits boxed BigInt. structuredClone(Object(1n)) therefore returns a plain empty object that is not a BigInt wrapper and has no usable primitive value.

Expected behavior

The clone should be a distinct boxed BigInt whose valueOf() matches the input. Native structuredClone follows this behavior.

まず React Native の structuredClone polyfill を見つけ、boxed Boolean、Number、String 値がどのように処理されているかを読んでください。structuredClone(Object(1n)) のカバレッジを追加し、結果が入力値と valueOf() が一致する、別個の boxed BigInt であることを検証してください。
