`Vercel Sandboxes` Persistence Is Now GA

Filesystem state now survives sessions by default. Long-running agent and preview workflows get simpler, but snapshot storage becomes a new cost line.

[ KEY POINTS ]
  1. Sandbox.create() now enables persistence by default, so files are saved and restored without manual snapshot handling.
  2. Each sandbox gets a customizable durable name. Sandbox.getOrCreate() adds idempotent retrieve-or-create for long-lived environments.
  3. Automatic snapshots consume separately billed snapshot storage. Use --non-persistent for throwaway jobs to avoid idle storage cost.
  4. Calling runCommand() or writeFiles() on a stopped sandbox resumes from the latest snapshot, which fits agent task handoff and preview reuse.
