#211 ci: add Python 3.13 to the test matrix

[Anonymous]

What

The CI test matrix (.github/workflows/ci.yml) currently runs python-version: ["3.11", "3.12"] on ubuntu-latest (plus a windows-latest / Python 3.12 include leg). Python 3.13 is released and users will run Doberman on it, so it should be tested too. Add "3.13" to the ubuntu matrix. The YAML edit is one line; the actual work is fixing whatever 3.13-only breakage surfaces once CI actually runs it (removed deprecations, stdlib changes) — that's unknown until you try, which is what makes this level-6 rather than level-1.

Difficulty: level-6

Tooling/CI/packaging change with an unknown-until-you-run-it payload — you may need to patch code for 3.13 stdlib changes (e.g. removed deprecated APIs) with no obvious diff to copy, and read CI failure output to find the fix.

Starting files

• .github/workflows/ci.yml — strategy.matrix.python-version (ubuntu leg) and the windows-latest include leg
• pyproject.toml — requires-python (currently >=3.11) and the classifiers list (currently lists 3.11 and 3.12)

Acceptance criteria

• [ ] "3.13" added to the ubuntu matrix in .github/workflows/ci.yml
• [ ] The 3.13 job is green in CI
• [ ] pyproject.toml classifiers updated to include Programming Language :: Python :: 3.13 (requires-python stays >=3.11)
• [ ] Any fix needed for 3.13 compatibility is minimal and does not regress 3.11/3.12
• [ ] existing behaviour unchanged
• [ ] ruff check . && ruff format --check . and lint-imports pass
• [ ] pytest passes

How to validate

pip install -e ".[dev]"
ruff check . && ruff format --check .
lint-imports
pytest --cov=doberman --cov-report=term-missing

Out of scope

• Dropping an existing Python version (3.11 or 3.12) from the matrix
• Changing the windows-latest leg (stays pinned to Python 3.12)
