 * @param reload - Function that fetches the latest state of the resource
 * @param isTerminal - Function that determines if the current state is terminal
 * @param transform - Function that transforms the resource into a new type
 * @param options - Configuration options for polling behavior
 * @returns The resource in its terminal state
 * @throws {TimeoutError} If the operation exceeds the timeout duration
 *
 * @example
 * const result = await wait(
 *   () => fetchOrderStatus(orderId),
 *   (status) => status === 'completed',
 *   (status) => status === 'completed' ? { status } : undefined,
 *   { timeoutSeconds: 30 }
