feat: Enhance RAG in a Box with multi-agent CoT and deployment options

Major enhancements:

- Add multi-agent Chain of Thought reasoning with specialized agents (Planner, Researcher, Reasoner, Synthesizer)

- Add support for both Oracle DB 23ai and local LLM (Ollama) deployments

- Implement containerized deployment with Podman for Windows/Mac/Linux

- Add comprehensive logging and error handling

- Add real-time step-by-step reasoning visualization

- Improve documentation with deployment guides and troubleshooting

- Add support for multiple container configurations

Technical improvements:

- Optimize agent prompts for faster responses

- Add proper error handling for database connections

- Add HuggingFace embeddings error recovery

- Improve container networking and initialization

+# AI RAG in a BOX Demo using Oracle Autonomous Database 23ai and Local LLMs
+
+## Introduction
+
+An innovative RAG (Retrieval Augmented Generation) system designed to leverage an LLM agent for effective information retrieval and response generation.
+
+This system efficiently processes various document formats and intelligently selects the appropriate knowledge base based on user queries.
+
+The AI RAG in a BOX Demo utilizing the Internal LLM Engine "Ollama" is deployable via Podman across multiple platforms, including Mac OSX, Windows, and Linux.
+
+AI RAG in a BOX Demo using Internal LLM Engine "Ollama" can be deployed in Podman on your PC - Mac OSX (Intel or ARM), Windows (Intel or ARM), or Linux.
+
+This solution includes 2 containers:
+- Oracle Database 23ai
+- AIRAG Container
+
+## 1. Install the containers
+
+#### Windows Deployment
+
+1. Install Podman in Windows
+   - Follow the installation guide [here](https://github.com/containers/podman/blob/main/docs/tutorials/podman-for-windows.md)
+   - See detailed tutorial for [Windows Installation](./install_win_llama3_db23ai.md)
+
+2. Install Containers
+   - Deploy using the script: [install_airagdb23ai_win.bat](./scripts/install_airagdb23ai_win.bat)
+
+#### Mac OSX Deployment
+
+- Deploy using the script. You can check all the steps which are commented in the script: [install_airagdb23ai_macosx.sh](./scripts/install_airagdb23ai_macosx.sh)
+
+#### Linux Deployment
+
+- Deploy using the script: [install_airagdb23ai_linux.sh](./scripts/install_airagdb23ai_linux.sh)
+
+## 2.Verifying Installation
+
+1. Check Podman network:
+
+```bash
+podman network ls
+```
+
+2. Verify downloaded images:
+
+```bash
+podman images
+```
+
+3. Check running containers:
+```bash
+podman ps
+```
+
+4. Check container logs:
+```bash
+podman logs -f 23aidb
+podman logs -f airagdb23aiinbox
+```
+
+5. Connect to the database:
+```bash
+podman exec -it 23aidb sqlplus VECDEMO/<pwd>@FREEPDB1
+```
+
+## Appendix: Troubleshooting
+
+### Database Connection
+
+To verify database functionality for the user `VECDEMO`:
+
+```bash
+podman exec -it 23aidb sqlplus VECDEMO/<pwd>@FREEPDB1
+```
+
+### HuggingFace Embeddings Error
+
+If you encounter this error:
+
+```bash
+OSError: We couldn't connect to 'https://huggingface.co' to load this file...
+```
+
+Restart the container:
+
+```bash
+podman stop airagdb23aiinbox
+podman start airagdb23aiinbox
+```
