Nova Forge SDK Reconciliation (v3.15.0)

Release: v3.15.0 (2026-06-22)
Packages: sagemaker 3.15.0 · sagemaker-core 2.15.0 · sagemaker-train 1.15.0 · sagemaker-serve 1.15.0 · sagemaker-mlops 1.15.0

This release converges the standalone Nova Forge SDK into the SageMaker Python SDK, making Nova model customization (training, evaluation, deployment) first-class under the sagemaker.* namespace.
