Automatic persistence now in beta on Vercel Sandbox

Vercel Sandboxes can now automatically save their filesystem state when stopped and restore it when resumed, removing the need for manual snapshots.

Key features:

• Automatic persistence separates storage from compute
• When stopped, session shuts down but filesystem is automatically snapshotted
• When resumed, new session boots from snapshot with no additional state storage charges
• Persistence enabled by default in beta SDK, can be disabled with persistent: false
• New methods for managing sandboxes: sandbox.update(), sandbox.listSessions(), sandbox.listSnapshots()
• Transparent session creation if a sandbox is stopped and a command runs

Sandboxes are now identified by unique customizable names.
