Workflow

Phase 1: Discover Clusters

Ask the user which region to target. Then use the AWS MCP to list all Redshift Serverless workgroups and provisioned clusters in that region. Present the list and ask which one(s) to migrate. Do NOT auto-discover across all regions — require the user to specify the region.
