Vercel Sandbox adds instant environment cloning via Sandbox.fork()

Vercel has introduced sandbox forking via Sandbox.fork(), allowing developers to instantly clone active sandboxes. The newly created sandbox starts from the source snapshot, inheriting configuration and environment variables for state branching and isolated testing.

// ANALYSIS

Instant environment forking is an essential building block for modern AI agents and speculative code execution workflows.

* Enables zero-overhead state branching for parallel test runs and multi-turn AI interactions.

* Preserves environment variables and config to eliminate repetitive setup boilerplate.

* Significantly improves execution speed when building interactive coding playgrounds and agentic sandboxes.
