💭 Nice feature, but currently i think the region is an explicity and mandatory config param, which we should also enforce in such a case.

The region inference from ARN was added for convenience since the ARN always contains the region (
arn:aws:bedrock-agentcore:REGION:ACCOUNT:harness/NAME). But I can make it mandatory for consistency with other AWS connectors.
