style(build-engine): fix indentation on Measure using/foreach blocks

The profile command wraps brace-less foreach embedded statements in
"using (Measure(...))" blocks; the loop bodies were left under-indented,
which dotnet format --verify-no-changes (the CI lint step) rejected,
turning main red. Re-indent so the format check passes. No behavior change.
