Worked on enhancing the apache/iceberg-rust repository by delivering a configurable SQL catalog initialization feature with improved name persistence and optional naming parameters. Utilized Rust for backend development, refactoring the SqlCatalogBuilder to ensure the supplied catalog name is correctly saved in SqlCatalogConfig. Addressed a bug where the catalog name was not retained before initialization, thereby improving reliability for downstream integrations. Updated and expanded the test suite to validate the new behavior and provide regression protection, aligning with related pull requests. These changes increased flexibility and usability for catalog initialization, reducing the risk of misconfiguration and supporting smoother client integrations.
