[sdialog] add RAG tutorial script and notebook

[ls-cnr]

Summary

This PR adds a colab tutorial and an example showing how to integrate a retrieval tool into an sdialog agent. We use our university counselling use case:

• tutorials/00_overview/8.counsellor_rag_agent.py
• tutorials/00_overview/8.rag_tool_integration.ipynb

I created these examples as a lightweight, practical introduction to tool-based RAG integration in sdialog.

Notes

• The example assumes a local retrieval server is available and ready to be invoked.
• No existing library behavior is changed.
