   * Interrupts the execution of a graph node.
   *
   * This function can be used to pause execution of a node, and return the value of the `resume`
   * input when the graph is re-invoked using `Command`.
   * Multiple interrupts can be called within a single node, and each will be handled sequentially.
   *
   * When an interrupt is called:
   * 1. If there's a `resume` value available (from a previous `Command`), it returns that value.
   * 2. Otherwise, it throws a `GraphInterrupt` with the provided value
   * 3. The graph can be resumed by passing a `Command` with a `resume` value
   *
   * Because the `interrupt` function propagates by throwing a special `GraphInterrupt` error,
   * you should avoid using `try/catch` blocks around the `interrupt` function,
   * or if you do, ensure that the `GraphInterrupt` error is thrown again within your `catch` block.
   *
   * @param value - The value to include in the interrupt.
   * @returns The `resume` value provided when the graph is re-invoked with a Command.
