Subject: [PATCH] ci: add GitHub Actions CI/CD workflow

Add a GitHub Actions workflow that runs on pull_request and push to main:
- Lint and format checks with ruff
- Unit tests with pytest (integration tests excluded to avoid LLM secrets)
- Matrix over Python 3.12 and 3.13 on ubuntu-latest
- DCO sign-off verification on PRs

Windows is excluded because the test suite has known path-separator
failures in build_context that are out of scope for this change.
