This pull request introduces two new CLI chat applications demonstrating DSPy fundamentals: a simple single-agent chat app (src/app.py) and a more advanced multi-agent orchestration app (src/multi.py). Both apps feature a rich terminal UI using the rich library, integrate external tools (weather, dice, coin flip), and showcase DSPy’s ReAct agent capabilities. The multi-agent app further demonstrates expert agent orchestration and intelligent routing.

New DSPy Chat Applications:

• Added src/app.py: A single-agent DSPy chat app with a conversational interface, tool usage (weather, dice, coin flip), and context/history management. The app uses DSPy’s ReAct agent and provides a rich CLI experience.
• Added src/multi.py: An advanced multi-agent DSPy chat app that introduces expert agents (Weather Expert, Games Expert) and an orchestrator agent to intelligently route user questions to the appropriate expert. Also features a rich CLI, tool integration, and conversation history.

Tool and Agent Integration:

• Both apps integrate external tools for weather lookup (using Open-Meteo API), dice rolling, and coin flipping, with robust error handling and result formatting. [1] [2]
• In src/multi.py, specialized expert agents are created for weather and games, each with custom signatures and personalities, and are orchestrated by a top-level agent for intelligent routing.

User Experience Enhancements:

• Both apps use the rich library for visually appealing panels, markdown rendering, and status spinners, enhancing the CLI chat experience. [1] [2]
• Conversation history is maintained and can be displayed on demand, improving usability and transparency. [1] [2]

DSPy Fundamentals Demonstrated:

• Apps showcase DSPy Signatures, Predictors, ReAct agent tool usage, and context/history management, making them educational examples for learning DSPy. [1] [2]
