Subject: [PATCH] Fix: Ensure response is generated when no tools are used

This commit addresses an issue where the system would not generate a response if a query did not trigger any tool usage while `useSpecificAPI` was enabled.

The fix involves two changes:

1.  The `while` loop condition in `app/actions.tsx` has been modified to remove the dependency on `toolOutputs.length`. This ensures that the application waits for a response (`answer`) to be generated, regardless of whether tools are used.
2.  The system prompt for the `researcher` agent in `lib/agents/researcher.tsx` has been enhanced to explicitly instruct the AI to provide a direct answer when no tools are necessary.

   When you use 'geospatialQueryTool', you don't need to describe how the map will change; simply provide your textual answer based on the query, and trust the map will update appropriately.
 
+When tools are not needed, provide direct, helpful answers based on your knowledge.
 Always aim to directly address the user's question. If using information from a tool (like web search), cite the source URL.
 Match the language of your response to the user's language.`;
