Hello Agent — Simplest possible agent

This sample creates a minimal agent using AzureOpenAIResponsesClient via an
Azure AI Foundry project endpoint, and runs it in both non-streaming and streaming modes.

There are XML tags in all of the get started samples, those are used to display the same code in the docs repo.

Environment variables:
  AZURE_AI_PROJECT_ENDPOINT        — Your Azure AI Foundry project endpoint
  AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME — Model deployment name (e.g. gpt-4o)
