/**
 * This React hook manages "resend" actions (e.g., resending a verification code) on ACUL screens.
 *
 * This hook:
 * - Tracks the remaining cooldown time.
 * - Tells you whether the resend button should be disabled.
 * - Provides a `startResend` function to trigger a resend immediately.
 *
 * @supportedScreens
 * - `email-identifier-challenge`
 * - `email-otp-challenge`
 * - `login-email-verification`
 * - `login-passwordless-email-code`
 * - `login-passwordless-sms-otp`
 * - `mfa-email-challenge`
 * - `mfa-sms-challenge`
 * - `mfa-voice-challenge`
 * - `phone-identifier-challenge`
 * - `reset-password-mfa-email-challenge`
 * - `reset-password-mfa-sms-challenge`
 * - `reset-password-mfa-voice-challenge`
 *
 * @param options - Optional configuration such as `timeoutSeconds` and `onTimeout`.
 *
 * @returns An object with:
 * - `remaining` — seconds left until the next resend is permitted.
 * - `disabled` — `true` if resending is currently blocked.
 * - `startResend` — call to initiate a resend immediately (if allowed).
 *
 * @example
 * ```tsx
 * import { useResend } from '@auth0/auth0-acul-react/mfa-sms-challenge';
 *
 * export function ResendButton() {
 *   const { remaining, disabled, startResend } = useResend({
 *     timeoutSeconds: 30,
 *     onTimeout: () => console.log('You can resend again'),
 *   });
 *
 *   return (
 *     <button onClick={startResend} disabled={disabled}>
 *       {disabled ? `Resend in ${remaining}s` : 'Resend Code'}
 *     </button>
 *   );
 * }
 * ```
 *
 * @remarks
 * - The underlying `ResendControl` has no explicit teardown method; the hook does not require manual cleanup.
 * - The hook re-initializes the resend manager if `timeoutSeconds` or `onTimeout` change.
