`Vercel Sandbox firewall` adds proxy forwarding and request filtering in beta

Outbound sandbox calls can now pass through your own proxy with path, method, query, and header matching. Useful for logging and credential control, but immediate reach is limited because it's beta on Pro and Enterprise.

[ KEY POINTS ]
  1. You can set a forwardURL on an allowed domain, and matching HTTPS requests are relayed to your own proxy for logging, debugging, or response transforms.
  2. Matchers can scope forwarding and credential brokering by path, method, query string, or headers, so only sensitive routes need extra handling.
  3. The proxy receives source metadata headers plus a vercel-sandbox-oidc-token, enabling request authentication and sandbox/team/project attribution.
  4. Access is limited to Pro and Enterprise beta and requires the @vercel/sandbox@beta SDK, so this is practical only if you already depend on Sandbox.
