…t switches - 新建 AnswerChatBot adapter component wraps @tdesign-react/chat ChatBot with the Answer backend contract: custom SSE parsing (markdown + thinking blocks from reasoning_content), vote actions bridged to the conversation vote API, conversation history rehydration. - The AI assistant page now renders AnswerChatBot; the legacy Sender/Bubble components stay for other pages. - 新建 site AI switches: home_chat_enabled (floating AI entry on the homepage) and home_chat_guest_enabled (logged-out visitors can chat; guest sessions stay client-side and are never persisted, voting off). - POST /chat/completions moves to the unauthenticated route group; the handler enforces the guest switch itself and runs guest sessions fully in memory with a system prompt prepended. - zh/en translations for the new switches and chat strings.
…stem prompt - Expose the assistant welcome text and a suggested-questions list (one per line) as site AI settings; both render inside the single welcome message as tappable chips, matching the TDesign reference layout. - Surface the existing prompt_config (zh/en system prompt) in the admin AI settings form, and always round-trip it on save so the backend no longer silently resets configured prompts to the built-in defaults. - Localize new admin labels and assistant strings (zh_CN/en_US). - apply refreshed language packs via i18next.addResourceBundle as soon as they are fetched instead of waiting for the next full page load. - fix new-chat reset: remount the ChatBot instead of swapping the omi message store in place, which crashed the action-bar re-render for conversations with completed messages; abort in-flight streams on reset and unmount. - fix suggestion chips: deliver clicks through per-message handle操作 (the installed tdesign-web-components has no directSend support).

For #1598
What
Modernize the AI assistant chat UI with TDesign React Chat and make the assistant's opening content admin-configurable, as proposed in #1598. Two commits:
feat: replace AI chat UI with TDesign React Chat and add homepage chat switchesAnswerChatBotadapter wiring the TDesignChatBotcomponent to Answer's existing/answer/api/v1/chat/completionsSSE contract:delta.contentstreams into a markdown block,delta.reasoning_contentinto a thinking block, with per-message voting, replay, and history rehydration when switching conversations.home_chat_guest_enabledswitch, logged-out visitors can chat; guest history stays client-side and voting is disabled.home_chat_enabled), reusing the same component.feat(ai): admin-configurable welcome text, suggested questions and system promptprompt_config(zh/en system prompt) is now editable in the admin AI settings form, and saving always round-trips it — previously an omitted prompt_config silently reset stored prompts to the built-in defaults.i18next.addResourceBundleas soon as they are fetched instead of waiting for the next full page load.Why
We self-host Answer as a community FAQ and wanted a streaming chat experience with thinking blocks, markdown and suggestion chips, plus control over what the assistant says and which tools the prompt advertises. TDesign React Chat provides the chat primitives; this patch keeps Answer's own backend contract unchanged apart from the guest gate and the new site-info fields.
Testing
go build ./...andgo test ./internal/schema ./internal/controllerNotes
tdesign-web-components@1.3.0-alpha.2does not implement suggestiondirectSend, so chip clicks are delivered through per-messagehandle操作and sent from the adapter. A one-line defensive guard for the component library'ssetExportpartsis applied in our deployment build; standard flows work without it.
