DSPy Prompt Optimization for Empathy

Use DSPy to create a signature for generating empathetic responses with Gemini 2.5 Pro. Apply this signature to optimize the 'Conversationalist' agent's ability to respond to user statements of distress or sadness, ensuring the responses are deeply empathetic and avoid generic phrases. Run a test where the companion responds to a user expressing emotional vulnerability, demonstrating the DSPy-enhanced empathy.
