Vercel Sandbox 2.2.0

Minor Changes

• Move the interactive shell server out of the sandbox and into the sandbox-controller. sandbox connect/ssh (CLI) and the new Sandbox.openInteractive() (SDK) now request a WebSocket URL and token from the API and connect to the controller-hosted PTY, instead of installing and bootstrapping the vc-interactive-server binary inside the sandbox at connect time. This removes the bundled server binary along with the @vercel/pty-tunnel and @vercel/pty-tunnel-server packages. (#222)

Patch Changes

• Upgrade Zod to v4 and update validators for Zod 4 compatibility. (#219)
