Subject: [PATCH] fix(layout): render PublicEnvScript as plain inline <script>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

next-runtime-env's <PublicEnvScript /> uses next/script beforeInteractive
internally. On Next.js error-page shells (<html id="__next_error__">),
beforeInteractive is not honored — the env script is serialized into the
RSC stream instead of being hoisted as a real <script> in <head>, so it
runs after client chunks evaluate. Any module that calls getBaseUrl()
at module-eval time (e.g. lib/auth/auth-client.ts) then crashes because
window['__ENV'] is still undefined.

disableNextScript renders a plain inline <script> in <head> that the
browser executes synchronously during HTML parse on every render path,
including error pages. Fixes "Application error: a client-side exception"
on 404 routes like /models/anthropic/xxx and /integrations/rand.
