 *
 * @example
 * ```typescript
 * const abortMiddleware = createAbortSignalMiddleware();
 * server.registerMiddleware(abortMiddleware);
 *
 * // In route handler:
 * const signal = ctx.abortSignal;
 * await longRunningOperation({ signal });
 * ```

 * request/response objects rather than the unified ServerContext.
 *
 * @param options - Optional configuration
 * @returns Express middleware function
 *
 * @example
 * ```typescript
 * // In Express adapter
 * app.use(createExpressAbortMiddleware());
 *
 * // Access in route handler
 * app.get('/api/stream', (req, res) => {
 *   const signal = res.locals.abortSignal;
 *   // Use signal for cancellation
