Motivation and Context

When I run the code on MacBook with the newest version uv 0.9.3 (83635a6c4 2025-10-15), uv gives the warning

warning: The tool.uv.dev-dependencies field (used in /Users/yukuan/Desktop/python-sdk/examples/servers/simple-auth/pyproject.toml, /Users/yukuan/Desktop/python-sdk/examples/servers/simple-pagination/pyproject.toml, /Users/yukuan/Desktop/python-sdk/examples/servers/simple-prompt/pyproject.toml, /Users/yukuan/Desktop/python-sdk/examples/servers/simple-resource/pyproject.toml, /Users/yukuan/Desktop/python-sdk/examples/servers/simple-streamablehttp/pyproject.toml, /Users/yukuan/Desktop/python-sdk/examples/servers/simple-streamablehttp-stateless/pyproject.toml, /Users/yukuan/Desktop/python-sdk/examples/servers/simple-tool/pyproject.toml) is deprecated and will be removed in a future release; use dependency-groups.dev instead

which says the current dev-dependencies field in multiple pyproject.toml files are deprecated. There is also related topic on the uv official website: https://docs.astral.sh/uv/concepts/projects/dependencies/#legacy-dev-dependencies

Therefore, I have replaced the deprecated dev-dependencies with dependency-groups, which addresses the warning.

How Has This Been Tested?

I have tested in MacOS 15.5 with uv 0.9.3 (83635a6c4 2025-10-15).
Also, I have cross checked with Windows 11 PC with earlier uv version uv 0.8.7 (10960bc13 2025-09-10).
