## Title

    Proposed fix: [DSPy] RuntimeError "Failed to save state to x.json ... Your DSPy program may contain non json-serializable objects" from module.save()

## Body

    Recommended action: Convert demo fields to JSON-serializable types, or save with a .pkl path / save_program=True (only load pickles you trust — DSPy warns .pkl can run arbitrary code).
    
    Option: Make state JSON-serializable or use .pkl for trusted use [evidence: official_recommended_action]
    Applies when: Saving optimized programs
    Steps:
    1. Convert custom objects in demos to dict/str
    2. or program.save("program.pkl")
    Expected: Program saved
    
    Evidence basis (self-declared by the contributing chat client): untested.
