Deploy Proof Assistant with Baseten

Prepare your LlamaIndex agent and Gemini 2.5 Pro integration for deployment. Use Baseten to serve your proof assistant as a scalable API endpoint. Provide the necessary configuration and code (e.g., a `predict.py` file) to deploy the model, ensuring efficient inference and access to the ChromaDB index (potentially by embedding ChromaDB or configuring external access). Detail the steps for creating a Baseten model and endpoint.
