Add greeting and property interest detection in message processing

- Enhanced `process_message` to prioritize greeting responses, providing a personalized welcome to users.
- Implemented detection for user interest in specific properties, allowing for tailored responses based on user queries about "property 1" and "property 2."
- Improved overall user engagement by offering detailed information about selected properties, streamlining the interaction flow and enhancing the user experience.
