Research direction
Look at the Python SDK build configuration and test suite to understand how new Python versions are added. Check the CI/CD pipelines for Python version matrices. The work involves updating version constraints, testing with Python 3.15 pre‑releases, and ensuring dependencies are compatible. 'Done' means the SDK builds and passes tests on Python 3.15.

Description
What would you like to happen?
Add support for Python 3.15 to the Beam Python SDK. The first full release of 3.15 is expected to be out on October 1, 2026. There is some delay expected between release and support for the version in Beam, as dependency libraries must also add support for 3.15.
