- Removed the query display section from the DatabaseQuery component to streamline the UI. - Updated the DatabaseQueryData interface to eliminate the query field, reflecting changes in tool result handling. - Enhanced the DatabaseQuery tool execution to focus on returning structured results without exposing raw SQL queries. - Added a new utility to strip <think> blocks from LLM outputs, improving content clarity and user experience.
