Changes: - Update TypeScript definitions to remove resolveWithObject from signal overloads - Add validation in toBuffer() to reject resolveWithObject when signal is present - Add tests to verify the new behavior This protects users from future breaking changes when resolveWithObject is deprecated and always set to true. Users can now use either signal (for cancellation) OR resolveWithObject (for structured output), but not both.
