Pull Request Overview

This PR adds support for the adapter.rename_relation method in the dbt adapter implementation. This allows dbt templates to rename database tables/relations through the adapter interface.

• Added abstract rename_relation method to the base adapter classes
• Implemented concrete rename_relation method in the runtime adapter that uses the engine adapter's rename_table functionality
• Added test coverage to verify the rename functionality works correctly
