The response now routes the new dashboard's `DashboardInfo` through `_sanitize_dashboard_info_for_llm_context` (same path as `dashboard_serializer`/`serialize_dashboard_object`), so title/description/chart/tag text is wrapped as untrusted before reaching LLM context. Added a test asserting the response title comes back LLM-context-wrapped. -- This is an automated message from the Apache Git Service.
