Motivation & Context

Agent Framework needs a Python example that runs agent-generated code in an Azure Container Apps Dynamic Sessions pool.

Description & Review Guide

• What are the major changes? Add a function-tool sample using existing HTTP and identity libraries, with application-owned session IDs, bounded execution/output, and setup guidance.
• What is the impact of these changes? The configured cloud pool executes code. Each program run owns a separate session, reuses it across tool calls, and obtains fresh tokens. The sample validates endpoints and surfaces HTTP errors.
• What do you want reviewers to focus on? Ruff and Pyright pass. HTTP mock checks cover the request contract, tokens, same-run reuse, cross-run isolation, endpoint rejection, and HTTP errors. Live Azure pool/model execution was not run.

The request contract was rechecked against Microsoft's 2025-10-02-preview Execute reference: the execution route/query, synchronous inline request fields, token scope, and response structure match the sample. The local HTTP mock verifies the client request and session/error behavior. Live pool/model execution has not been run and remains an integration-validation limitation, as stated in the PR description.
