/**
* Gets the appropriate aria-invalid value for form components.
*
* This utility handles cross-framework compatibility by checking for an explicit
* aria-invalid attribute on the host element first, then falling back to the
* component's state. It properly handles both string and boolean values that
* may be passed from different frameworks (especially React).
*
* @param host - The host element to check for aria-invalid attribute
* @param state - The component's state ('error', 'success', 'default')
* @returns The aria-invalid value as a string ('true' or 'false')
*
