Signing up refreshes the session, which briefly routes /onboarding to
/sign-in without a return path; the sign-in route then sent the new
account to /app. The shell's own redirect to onboarding was skipped
whenever a focus refresh landed before the bootstrap response, so a
fresh account could stay on an empty Today view.
/onboarding now sends signed-out visitors to /sign-in?next=/onboarding
and sign-in honours it, and the shell redirects an account without
any bots or conversations regardless of which refresh landed first.
Without a connected model nothing can reply, so the composer shows a
"Connect model" action that opens model settings instead of a send
error after the fact.
