README docs with getting started examples

I do not have permissions for PRs, below is what I would add to the end of the current README

🚀 Getting Started

The MCP Server lets you interact with h2oGPTe via plain language. It can perform multi-step tasks like ingesting websites, creating collections, and running LLM agents — all from a single chat prompt.

✨ Example: Create a Safeway Grocery Store Demo

You can say:

Help me create a demo for Safeway grocery store.
First, make a collection with a good name and description.
Then, ingest 10 pages of their website with summaries and sample questions.
Then, create a chat session and ask one of the sample questions.
Then, make a new chat session and ask for a plot of the parent company’s stock over the last 3 years using llm_args use_agent = True

The server will handle all the steps for you — no need to write code.
