Share Vercel Container Registry repositories across teams

Vercel Container Registry now supports cross-team repository sharing, allowing teams to grant read-only access to their container images. Sharing is read-only and covers entire repositories — recipients can pull and use images but cannot push, delete, or re-share. Each repository can be shared with up to 100 teams. Configuration is available via the project dashboard or the Vercel CLI (v58.3.0+). Shared images can also be referenced in Vercel Sandbox via a team-scoped image reference in `Sandbox.create()`. The feature is available on all plans.
