Mutation: cross-package coverage regression test Add 'sydtest-mutation-example-cross', a library with no test suite of its own, covered only by 'Example.CrossLibSpec' in the separate 'sydtest-mutation-example-gen' package. The new 'mutation-sydtest-mutation-example-cross' check (libraries = [cross], tests = [example-gen]) asserts the per-library report attributes that cross-package coverage and kills the mutations; before the fix it reported them uncovered. Built green: Killed 36 / Survived 0 / Uncovered 0 / Skipped 0.
