 * React hook for subscribing to an Alwatr trigger and executing callbacks.

 *
 * // Basic usage
 * function DataList() {

 *     useTrigger(refreshTrigger, useCallback(() => {

  }, []));
 *
 *   return <div>{data.map(item => <Item key={item.id} {...item} />)}</div>;
 * }
 *
 * // With subscription options
 * function ConditionalRefresh() {
 *   useTrigger(
 *     refreshTrigger,
 *     () => console.log('Refreshed!'),
 *     { once: true } // Only trigger once
