Two sites reached a registry for the vendored framework, which the rescope
turns from a silent second copy into a hard failure.
Live-link mode relinked only the root manifest, so a generated workspace member
— `plugins/*/package.json` — resolved its own dependencies from the registry
and installed upstream cordis beside this repository's vendored copy.
`LinkWorkspace.relinkNestedManifest()` relinks every nested generated manifest;
`peerDependencies` keeps its range because package managers reject a link spec
there.
The sandbox publish-path rehearsal installs this repository's vendored cordis
and cosmokit tarballs instead of naming a registry version.
