 * 1. Validate pod and target node exist
 * 2. Update the Pod routing assignment to the target node

 * Data does NOT need to be copied upfront:
 * - Metadata is in shared PostgreSQL (Quadstore), already accessible from all nodes
 * - Binary files use presigned URL redirect (302) from object storage
 *
 * This provides instant, user-transparent migration.
