Pull request overview

This PR introduces automated YAML formatting via pre-commit and applies the formatter’s output to existing YAML files to normalize whitespace/blank lines.

Changes:

• Add the google/yamlfmt hook to .pre-commit-config.yaml to enforce YAML formatting in pre-commit.
• Reformat multiple YAML files (configs + GitHub workflows) by removing stray/empty whitespace-only lines to match the formatter’s style.
