chore: add Dependabot and test across Python 3.10-3.14

[stephen-kintsugi]

Summary

• Add .github/dependabot.yml: weekly updates for Python (Poetry, via pyproject.toml/poetry.lock) and GitHub Actions, grouped patch/minor, majors ignored.
• Declare Python 3.13 and 3.14 support via trove classifiers (the package targets >=3.10).
• Default CI to Python 3.13 and add a test-matrix job running the suite on 3.10, 3.11, 3.12, 3.13, and 3.14 (fail-fast: false), so every supported version is exercised. Releases are gated on the matrix.

Notes

• Runner stays ubuntu-latest (GitHub-hosted), appropriate for a public repository.
• If a dependency is not yet ready on 3.14, that matrix cell will surface it; we can pin or cap then.

Note

Low Risk
Changes are limited to CI, Dependabot, and version/classifier metadata with no modifications to hook or library behavior.

Overview
Adds Dependabot via .github/dependabot.yml for weekly Poetry/pip updates (grouped patch/minor, majors ignored) and GitHub Actions bumps, with cooldowns and dependency labels.

CI now defaults the shared setup action to Python 3.13 (was 3.12) and introduces a test-matrix job that runs pytest on 3.10 through 3.14 with fail-fast: false. auto-tag must pass both lint-and-test and test-matrix before tagging releases.

Package metadata bumps to 0.3.6 and adds PyPI classifiers for 3.13 and 3.14; runtime dependency remains python >= 3.10.

Dependabot tightens broad constraint

Medium Severity

versioning-strategy: increase always raises lower bounds to match new versions, so Dependabot would gradually tighten the intentionally broad squawk-cli = ">=2.0" constraint in pyproject.toml. That can conflict with consumers who pin their own squawk version via additional_dependencies.

 

^{Triggered by learned rule: squawk-cli broad version constraint is intentional}

PR Risk Assessment

Risk level: Very Low
Review required: No
Action taken: Approved

Rationale

Per-cluster assessment (max across clusters = PR tier):

1. Dependabot config (.github/dependabot.yml): Weekly pip and GitHub Actions update automation only. No runtime behavior change; trivially reversible by deleting or editing the file. Very Low.
2. CI / release gating (.github/workflows/ci.yml, .github/actions/setup-python-poetry/action.yml): Adds a Python 3.10–3.14 test matrix, bumps the default CI Python to 3.13, and gates auto-tag on the matrix. CI-only tooling with no shared-resource or production blast radius. Very Low.
3. Package metadata (pyproject.toml classifiers + version bump, squawk_alembic/__init__.py version constant): Metadata-only edits; no hook or library logic changed. Very Low.

No production logic was modified, so no new tests are required. All CI checks (including the new matrix jobs on 3.10–3.14) are passing.

risk_level: Very Low
review_required: false
reviewers: []
action_taken: approved
rationale: Changes are limited to Dependabot config, CI test-matrix/default Python version, and package metadata (version bump + PyPI classifiers). No production hook/library logic was modified; all matrix CI jobs pass.
