• Updates code_format and test jobs to only run when code changes are detected
• Improves CI efficiency by skipping expensive test matrix when only documentation is updated

Benefits

• Faster CI runs for documentation-only PRs
• Reduced resource usage and costs
• Maintains all existing functionality for code changes

• Verify CI runs normally for code changes
• Verify CI skips tests for documentation-only changes
