Add scripts and documentation for local inference configuration with Ollama and mlx-omni-server

- Introduced `configure_local_inference.sh` to automatically set `.dev.vars` based on active local inference services.
- Updated `start_inference_server.sh` to handle both Ollama and mlx-omni-server server types.
- Enhanced `package.json` to include new commands for starting and configuring inference servers.
- Refined README to include updated instructions for running and adding models for local inference.
- Minor cleanup in `MessageBubble.tsx`.
