[mishushakov]

Summary

• Update setup-python action from v4 to v6 to support Python 3.13

Affected Workflows

• lint.yml
• performance_tests.yml
• python_tests.yml
• release.yml (multiple jobs)
• release_candidates.yml

Note

Low Risk
CI-only change that bumps the Python runtime and actions/setup-python version; main risk is workflow breakage if dependencies/tools don’t yet support Python 3.13.

Overview
Updates GitHub Actions workflows to run Python jobs on Python 3.13 (including linting, tests, performance tests, and release/release-candidate pipelines), replacing prior 3.10/3.12 usage.

Upgrades actions/setup-python from v4 to v6 across these workflows to support the new Python version.

NumPy 1.26.4 incompatible with Python 3.13 in charts

High Severity

The chart_data_extractor project depends on numpy = "^1.26.4" (constrained to <2.0.0), but NumPy 1.26.4 has Requires-Python: <3.13,>=3.9 and is the last 1.x release. Upgrading Python to 3.13 makes it impossible to install numpy within that version constraint, so poetry install will fail. The pyproject.toml constraint needs to be updated to allow NumPy 2.x before switching to Python 3.13.

NumPy 2.0.2 lacks Python 3.13 support in SDK

High Severity

The python/poetry.lock pins numpy to 2.0.2, which has no cp313 wheels. NumPy 2.1.0 was the first version to add Python 3.13 support (per its release notes). On Python 3.13, Poetry would fall back to building numpy 2.0.2 from source, which is expected to fail because the C code was not updated for Python 3.13 API changes. This breaks python_tests.yml, performance_tests.yml, and lint.yml at poetry install.
