chore: update Cargo.lock and fix formatting for CI

- Update Cargo.lock to include test-log dependency changes
- Fix formatting (remove extra blank line in test function)
- Resolves CI build failure with --locked flag

This addresses the CI error:
"the lock file needs to be updated but --locked was passed"
