feat: add support for Python 3.13 and 3.14

[curfew-marathon]

Summary

Brings the SDK's tested and advertised Python versions in line with the OpenFGA Language & Framework Version Support Policy.

The policy requires supporting every Python version currently in the bug-fix or security-fix phase per the Python Developer's Guide. As of this change the
supported set is 3.10, 3.11, 3.12, 3.13, 3.14. The repo previously only covered 3.10–3.12, leaving the two newest actively-developed releases (3.13 and 3.14, both in the bug-fix phase) untested and
unadvertised.

Changes

• .github/workflows/main.yaml — add 3.13 and 3.14 to the test job's python-version matrix.
• pyproject.toml — add the Programming Language :: Python :: 3.13 and :: 3.14 trove classifiers.

Policy alignment

Python	Phase (Jun 2026)	Before	After
3.10	security	✅	✅
3.11	security	✅	✅
3.12	security	✅	✅
3.13	bugfix	❌	✅
3.14	bugfix	❌	✅
3.9	EOL (Oct 2025)	—	— (correctly excluded)

Intentionally unchanged

• requires-python = ">=3.10" — floor stays at the oldest supported version; 3.9 is EOL.
• target-version = "py310" (ruff) and python_version = "3.10" (mypy) — these target the minimum supported version for lint/type-check, which is correct.
• The single-version steps (ruff/codecov gate, publish) remain pinned to 3.10.
• .snyk interpreter pin (3.10.6) — scanner resolves deps against the floor version; left as-is.

Notes

• The test matrix also has a urllib3-version axis (1.26.19, 2.2.2), so this adds 4 new CI cells (2 Python × 2 urllib3).
• aiohttp is unpinned (>=3.9.3); the lockfile already resolves aiohttp 3.14.x, which ships 3.13/3.14 wheels.

Test plan

• CI matrix passes on the new 3.13 and 3.14 cells (both urllib3 variants)
• urllib3==1.26.19 (pinned legacy line) installs and imports cleanly on 3.13 and 3.14
• Package builds and classifiers render correctly on PyPI metadata

Summary by CodeRabbit

• Chores
  • Expanded CI test coverage to run against newer Python versions, including 3.13 and 3.14.
  • Updated supported Python version metadata to reflect the added version compatibility.
