/**
* Handles agent interrupts (`on_interrupt`) with optional filtering, preprocessing, and resume behavior.
*
* The hook listens to custom events on the active agent, stores interrupt payloads per run,
* and surfaces a render callback once the run finalizes. Call `resolve` from your UI to resume
* execution with user-provided data.
*
* - `renderInChat: true` (default): the element is published into `<CopilotChat>` and this hook returns `void`.
* - `renderInChat: false`: the hook returns the interrupt element so you can place it anywhere in your component tree.
*
* `event.value` is typed as `any` since the interrupt payload shape depends on your agent.
* Type-narrow it in your callbacks (e.g. `handler`, `enabled`, `render`) as needed.
*
* @typeParam TResult - Inferred from `handler` return type. Exposed as `result` in `render`.
* @param config - Interrupt configuration (renderer, optional handler/filter, and render mode).
* @returns When `renderInChat` is `false`, returns the interrupt element (or `null` when idle).
* Otherwise returns `void` and publishes the element into chat. In `render`, `result` is always
* either the handler's resolved return value or `null` (including when no handler is provided,
* when filtering skips the interrupt, or when handler execution fails).
*
* @example
* ```tsx
* import { useInterrupt } from "@copilotkitnext/react";
*
* function InterruptUI() {
*   useInterrupt({
*     render: ({ event, resolve }) => (
*       <div>
*         <p>{event.value.question}</p>
*         <button onClick={() => resolve({ approved: true })}>Approve</button>
*         <button onClick={() => resolve({ approved: false })}>Reject</button>
*       </div>
*     ),
*   });
*
*   return null;
* }
* ```
*
* @example
* ```tsx
* import { useInterrupt } from "@copilotkitnext/react";
*
* function CustomPanel() {
*   const interruptElement = useInterrupt({
*     renderInChat: false,
*     enabled: (event) => event.value.startsWith("approval:"),
*     handler: async ({ event }) => ({ label: event.value.toUpperCase() }),
*     render: ({ event, result, resolve }) => (
*       <aside>
*         <strong>{result?.label ?? ""}</strong>
*         <button onClick={() => resolve({ value: event.value })}>Continue</button>
*       </aside>
*     ),
*   });
*
*   return <>{interruptElement}</>;
* }
* ```
