DSPy Program Design for Code Generation

Design a DSPy program that orchestrates multiple LLM calls for the 'Code Generation' task. Define the signature for generating an initial code draft, then another signature for refining the code based on static analysis feedback (e.g., linting errors, security warnings). Specify how different LLMs (OpenAI o3, Hugging Face Hub models) would be integrated into different stages of this DSPy program.
