Mutation phase: take a MutationRunSettings record, not positional args runMutationMode took six positional arguments including two adjacent Bools (failFast, emitRedundancy) that could be swapped with no type error. Replace them with a named MutationRunSettings record so each field is set by name at the call sites (runDriver, runDiff, the test). Pure refactor; behaviour unchanged.
