Add direct summary response for property listings in chat_with_session_memory

- Implemented logic to provide a direct summary of property listings when the user queries for available options, enhancing user interaction and experience.
- The summary includes key property details such as title, location, size, and price, along with links to listings, improving the clarity of responses.
- Updated the response structure to ensure users receive relevant information promptly when specific triggers are detected in their queries.
