[jsjiang]

@datadavev @sfisher Hi Dave and Scott,
Here are the major changes:

• Upgrade Python to 3.11 as 3.10 will be end of life 2026-10
• Upgrade fastapi to >=0.116.0 so packages such as starlette and idna can be updated to newer versions to fix Dependabot security alerts.

Please review and let me know if have questions.

Thank you

Jing

Looks OK - the version changes don't appear to create any conflict or other issues.

This looks ok to me though I don't know if I tested thoroughly.

I was able to update, (uv sync I think?) and to start the application (though I think maybe I'm missing something or it doesn't like http?) and I was able to run tests successfully (uv run pytest).

I'm sure Dave knows better than me, but it seems to be probably working fine.
