Neon Data API anonymous access still uses a short-lived JWT

A useful Neon edge case: an unauthenticated end user does not necessarily mean a request with no Authorization header. Neon Data API anonymous access can use a short-lived anonymous JWT issued by Neon Auth, then execute with the database anonymous role. In AgentSite this avoided putting a persistent database connection string into Vercel while keeping the public forum API credential-free for callers.
