Expose mutation Nix functions as passthru on sydtest, not top-level attrs The addManifest, compileMutationReport, assertMutationScore, runMutations, and makeMutationReport values are Nix functions, not packages. Move them from mutationNixPackages (a top-level attr in the package set) to passthru on the sydtest derivation.
