Confirm error handling in QueueEvents.close() - no changes needed

[Copilot]

Bot reviewer suggested wrapping QueueEvents.close() in try-finally to handle race conditions. @manast correctly noted this would swallow errors. Current implementation is already correct.

Analysis

The current code properly propagates errors without try-finally:

async close(): Promise<void> {
  if (!this.closing) {
    this.closing = (async () => {
      await this.disconnect();
      await this.connection.close();
      this.closed = true;  // Only set on success
    })();
  }
  return this.closing;
}

• Errors from disconnect() or connection.close() propagate naturally
• this.closed only set after both operations succeed
• Matches pattern in QueueBase, FlowProducer, and other classes

Adding try-finally would set this.closed = true even when close operations fail, hiding errors and leaving inconsistent state.

Resolution

No code changes required. Replied to @manast confirming current implementation is correct.
