/**
 * useStreamConnection - React hook for SSE connections
 *
 * Features:
 * - Auto-connect on mount
 * - Auto-reconnect on disconnect
 * - Channel subscription via query params
 * - Message event handling
 * - Connection state management
 *
 * @example
 * ```tsx
 * function UploadProgress({ fileId }: { fileId: string }) {
 *   const [progress, setProgress] = useState(0);
 *
 *   // Use generic to get properly typed message.data
 *   const { connected, error } = useStreamConnection<FilesUploadStreamProgress>({
 *     channels: [`upload:${fileId}`],
 *     onMessage: (message) => {
 *       if (message.event === 'progress') {
 *         // message.data is typed as FilesUploadStreamProgress
 *         setProgress(message.data.percentage);
 *       }
 *     },
 *   });
 *
 *   if (error) return <div>Connection error</div>;
 *   if (!connected) return <div>Connecting...</div>;
 *
 *   return <div>Progress: {progress}%</div>;
 * }
 * ```
