The Landlock platform packages sit behind optionalDependencies, and npm fails
the install on their 404 rather than skipping them: they belong to the native
sequence, whose pack needs a musl toolchain and one build per architecture, so
this job cannot produce them and holds no credentials to fetch them. A consumer
that cannot install them must still start, which is what optional means here.
The release spec also gains block bodies where the lint rule rejects returning a
void expression from an arrow shorthand.
