Resolve conflicts with the independently-merged ai-agent-roles feature: - ai-chat.module.ts: keep BOTH AiAgentRolesModule and the public-share wiring (Share/Search modules, PublicShareChatController, services). - ai.service.ts: take develop's getChatModel ChatModelOverride superset, which already covers the public-share model-id-only override.
