Reject repeated pagination tokens.

If DescribeInstances returns a non-empty token that was already used, this loop requests another page indefinitely. The scan can hang and continue accumulating resources. Track used tokens and return the collected resources with an error when a token repeats. Alibaba documents NextToken as the token for the subsequent page. (alibabacloud.com)

Based on learnings, “detect and reject responses where the server indicates more pages … but the returned end cursor is unchanged from the previous request.”

Review comment at @pkg/providers/alibaba/instances.go at line 55:
In the DescribeInstances pagination loop, track tokens already used and, when a
non-empty NextToken repeats, return the resources collected so far with an error
instead of requesting another page.
