I believe the build error is unrelated to the changes comprised of this PR!

AI OVERVIEW:

Summary: This is a breaking API change in the @crossmint/wallets-sdk package that affected the React Native UI package. The ShadowSignerStorage interface's keyGenerator method signature was changed from accepting a chain parameter to accepting no parameters, but the React Native implementation wasn't updated.
This error is blocking your build and is unrelated to your changeset changes. You'll need to fix the type mismatch before you can successfully build the project.
