style: space after spread operator for ReSharper 2026.2

ReSharper 2026.2 normalises `..x` to `.. x` in collection expressions, so
cleanupcode rewrote this line and the CI format gate failed. Apply the
formatting the tool now produces; it already matches the spread style used
elsewhere in the tests.
