Code Review

This pull request applies ruff formatting to a new batch of files under vllm-ascend/. The changes primarily consist of style updates, such as modernizing type hints (e.g., using list instead of typing.List and | for unions), adjusting line breaks to meet length constraints, and reformatting imports. The configuration in pyproject.toml has been updated to include these files in the linting process. The changes are consistent and correctly apply modern Python formatting without introducing any apparent functional issues. The code is cleaner and more consistent with the project's style guidelines.
