–New PRO feature: Guest AI Search — let visitors who are not logged in use the assistant (opt-in, off by default).
–Guests are protected by a per-day site limit, per-IP throttling, optional Cloudflare Turnstile verification, and a "register after N messages" prompt — so they can never drain your credits or block your logged-in shoppers.
–A guest's conversation is carried over to their account when they register or log in.
–New "Guest access" settings in the Credits & Limits tab (enable, daily limit, free messages before registration, Turnstile keys).
