A single authenticated render called auth() 4-5 times (access guard, site
layout, both permission loaders, the page itself), and every call re-parsed
the session cookie, decoded and HMAC-verified the JWT and ran the jwt/session
callbacks. Wrapping NextAuth's handler in React's cache scopes that work to
one verification per request.
Outside a render (scripts, jobs worker) React's cache is a pass-through, so
those call sites behave exactly as before.
