Eduard van Valkenburg 5e056b672e Python: [BREAKING] Python: Provider-leading client design & OpenAI package extraction (#4818 )

* Python: Provider-leading client design & OpenAI package extraction

Major refactoring of the Python Agent Framework client architecture:

- Extract OpenAI clients into new `agent-framework-openai` package
- Core package no longer depends on openai, azure-identity, azure-ai-projects
- Rename clients for discoverability: OpenAIResponsesClient → OpenAIChatClient,
  OpenAIChatClient → OpenAIChatCompletionClient
- Unify `model_id`/`deployment_name`/`model_deployment_name` → `model` param
- New FoundryChatClient for Azure AI Foundry Responses API
- New FoundryAgent/FoundryAgentClient for connecting to pre-configured Foundry agents
- Remove OpenAIBase/OpenAIConfigMixin from non-deprecated client MRO
- Deprecate AzureOpenAI* clients, AzureAIClient, OpenAIAssistantsClient
- Reorganize samples: azure_openai+azure_ai+azure_ai_agent → azure/
- ADR-0020: Provider-Leading Client Design

* fix: missing Agent imports in samples, .model_id → .model in foundry_local sample

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* fix: CI failures — mypy errors, coverage targets, sample imports

- azure-ai mypy: add type ignores for TypedDict total=, model arg, forward ref
- Coverage: replace core.azure/openai targets with openai package target
- project_provider: add type annotation for opts dict

Get Started with Agent Framework for Python

This folder contains a progressive set of samples that introduce the core concepts of Agent Framework one step at a time.

Prerequisites

pip install agent-framework --pre

Set the required environment variables:

export AZURE_AI_PROJECT_ENDPOINT="https://your-project-endpoint"
export AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME="gpt-4o"   # optional, defaults to gpt-4o

Samples

#	File	What you'll learn
1	01_hello_agent.py	Create your first agent and run it (streaming and non-streaming).
2	02_add_tools.py	Define a function tool with `@tool` and attach it to an agent.
3	03_multi_turn.py	Keep conversation history across turns with `AgentSession`.
4	04_memory.py	Add dynamic context with a custom `ContextProvider`.
5	05_first_workflow.py	Chain executors into a workflow with edges.
6	06_host_your_agent.py	Host a single agent with Azure Functions.

Run any sample with:

python 01_hello_agent.py

These samples use Azure Foundry models with the Responses API. To switch providers, just replace the client, see all providers
