The init workflow installs a local react-native-macos tarball, but that package depends on @react-native-macos/virtualized-lists@0.81.8, which is not published to npm yet.\n\nPack and install virtualized-lists locally before installing react-native-macos, so the dependency graph is resolved from local artifacts during PR validation.\n\nCo-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
