build(release): make the release set publishable under the private scope

Every package under packages/, apps/, and vendor/ drops "private": true and
declares publishConfig.access "restricted": the repository now states which
packages it publishes instead of deciding it at publish time. Each one also
declares its repository and directory, which is how a consumer of a private
package reaches its source.

The Landlock packages move to restricted with them. They have never been
published, so nothing anonymous depends on them today, and the whole
@deepseek-ai scope stays private.

The workspace constraint that required every package to be private now applies
to non-members only, and asserts the publishable trio on each release member.
