Implement Data Gathering Agent

Implement the 'Geopolitical Analyst' agent within your AutoGen setup. This agent should be capable of using the **Linkup** API to search for recent news and reports related to a given geopolitical event (e.g., 'AI in defense cooperation' or 'international data sharing agreements'). The agent should be able to summarize its findings using the **Alibaba Cloud Qwen** model and share them with other agents. Include necessary Python code for API interaction and Qwen model invocation.
