Foundry Agent — Custom client configuration

This sample demonstrates three ways to customize the FoundryAgent client layer:

1. Default: FoundryAgent creates a RawFoundryAgentChatClient (full middleware) internally
2. client_type: Pass RawFoundryAgentChatClient for no client middleware
3. Composition: Use Agent(client=RawFoundryAgentChatClient(...)) directly

Environment variables:
    FOUNDRY_PROJECT_ENDPOINT — Azure AI Foundry project endpoint
    FOUNDRY_AGENT_NAME       — Name of the agent in Foundry
    FOUNDRY_AGENT_VERSION    — Version of the agent
