Motivation & Context

The ChatKit integration README's backend setup asks for AZURE_OPENAI_ENDPOINT, AZURE_OPENAI_API_VERSION and AZURE_OPENAI_MODEL, but app.py creates its agent with FoundryChatClient(credential=AzureCliCredential()) (imported from agent_framework.foundry). That client reads FOUNDRY_PROJECT_ENDPOINT and FOUNDRY_MODEL (env_prefix="FOUNDRY_") and ignores the AZURE_OPENAI_* variables, so following the README fails at startup with Model is required. Set via 'model' parameter or 'FOUNDRY_MODEL' environment variable. The install line also omits agent-framework-foundry, which provides agent_framework.foundry.FoundryChatClient (agent-framework-chatkit only depends on agent-framework-core), so the import fails first.

Description & Review Guide

• What are the major changes? In python/samples/05-end-to-end/chatkit-integration/README.md:
  • backend step 2 now exports FOUNDRY_PROJECT_ENDPOINT and FOUNDRY_MODEL instead of the AZURE_OPENAI_* variables;
  • the pip install line adds agent-framework-foundry;
  • the prerequisite reads "A Microsoft Foundry project with a deployed model".
• What is the impact of these changes? Documentation only; the sample code is unchanged.
• What do you want reviewers to focus on? app.py line 34 (from agent_framework.foundry import FoundryChatClient) and line 225 (FoundryChatClient(credential=AzureCliCredential())), and RawFoundryChatClient.__init__ in packages/foundry/agent_framework_foundry/_chat_client.py.

N/A - trivial change. Stale setup instructions in one sample README; the correction follows what the existing sample already uses, with no behavior change.
