fix(tutorials): add pytest-asyncio to async tutorial dev deps

[deepthi-rao-scale]

Problem

The Run Integration Tests jobs for four async SDK tutorials fail at pytest collection:

ERROR collecting tests/test_agent.py
ModuleNotFoundError: No module named 'pytest_asyncio'
1 error during collection  (exit code 2)

Tutorial tests run via docker exec <agent> pytest tests/test_agent.py inside the agent image. These tutorials' tests/test_agent.py import pytest_asyncio and use @pytest_asyncio.fixture, but the dependency is provided nowhere: it's not in their pyproject dev extras, and the image installs only .[dev].

Fix

Declare pytest-asyncio and httpx in each affected tutorial's dev optional-dependencies, so uv pip install .[dev] picks them up. This matches the tutorials that already run their async tests correctly (e.g. 110_pydantic_ai, all of 00_sync), and keeps the test deps with the project — so pytest also works when run locally, not just inside the built image.

 dev = [
     "pytest",
+    "pytest-asyncio",
+    "httpx",
     "black",
     "isort",
     "flake8",
 ]

Affected tutorials:

• 10_async/00_base/090_multi_agent_non_temporal (latent — not currently in the CI matrix)
• 10_async/10_temporal/060_open_ai_agents_sdk_hello_world
• 10_async/10_temporal/070_open_ai_agents_sdk_tools
• 10_async/10_temporal/080_open_ai_agents_sdk_human_in_the_loop
• 10_async/10_temporal/090_claude_agents_sdk_mvp

How the set was determined

Enumerated every tutorial whose test_agent.py imports pytest_asyncio, then kept only those where neither the pyproject dev extras nor the Dockerfile provide it — exactly the four red CI jobs plus one latent case.

Greptile Summary

This PR fixes pytest collection failures in five async tutorial packages by declaring pytest-asyncio and httpx as dev optional-dependencies in each tutorial's pyproject.toml. Without these entries, uv pip install .[dev] inside the agent image omitted both packages, causing an immediate ModuleNotFoundError when pytest tried to collect test_agent.py.

• Adds pytest-asyncio and httpx to the [project.optional-dependencies] dev section of five pyproject.toml files across 10_async/00_base/090_multi_agent_non_temporal and four 10_async/10_temporal/0{60..90}_* tutorials.
• Matches the pattern already used by tutorials that pass CI (e.g. 110_pydantic_ai), keeping test dependencies co-located with the project for both local and Docker-based runs.

Confidence Score: 5/5

All five files receive an identical, minimal additive change to dev-only dependencies; no production code or runtime behaviour is touched.

Every change is a two-line addition of well-known test tooling to dev optional-dependencies. The fix directly mirrors the working pattern used by other tutorials in the same repo, the test files confirm both imports are required, and there is no risk of side effects on the installed agent images in production.

Files Needing Attention: No files require special attention; all changes are confined to dev dependency declarations in tutorial pyproject.toml files.
