Fix coverage workflow install and expand Ubuntu CI test matrix

[Copilot]

The coverage Actions job was failing before tests started because it invoked maturin develop without an active virtualenv. This change makes the job follow a packaging path that works in CI, adds an Ubuntu-only pytest matrix across all currently supported Python versions, and updates the workflow actions to current major versions while preserving the existing wheel-matrix jobs.

• Root cause

  • maturin develop --release --extras test requires a virtualenv or conda environment.
  • The new coverage job ran it directly in the runner environment, so the job exited during setup.

• Workflow changes

  • Add a dedicated Ubuntu-only pytest job matrix for Python 3.10, 3.11, 3.12, 3.13, and 3.14.
  • Keep the dedicated coverage job on Linux/Python 3.12.
  • Replace the maturin develop step with an editable install:
    • python -m pip install -e .[test]
  • Generate HTML, Markdown, and XML coverage reports with line-level detail.
  • Upload all three reports together as the coverage-reports artifact.

• GitHub Actions updates

  • Update actions/checkout to v6.
  • Update actions/setup-python to v6.
  • Update actions/upload-artifact to v7.
  • Update actions/download-artifact to v8.
  • Update actions/attest-build-provenance to v4.
  • Update uraimo/run-on-arch-action to v3.

• Dependency updates

  • Add pytest-cov to the test optional dependency group in pyproject.toml.
  • This keeps the coverage job aligned with the repo's existing test extras instead of introducing a separate install path.

• Resulting CI path

@copilot the uploaded coverage report is really minimal and unhelpful (see below)- I would like html and markdown reports as well with line coverage so I can see which lines hit and which miss.

Done in the latest commit. The coverage job now generates three report formats:

• --cov-report=html → htmlcov/ directory (browsable per-file line coverage)
• python -m coverage report --format=markdown > coverage.md → coverage.md (Markdown table with Stmts/Miss/Cover columns)
• --cov-report=xml → coverage.xml (kept for tooling compatibility)

All three are bundled in the coverage-reports artifact uploaded at the end of the job.

Addressed in 6601028. The workflow now adds an Ubuntu-only pytest matrix for Python 3.10-3.14, keeps coverage on Python 3.12, and updates the GitHub Actions versions to their latest major releases.

Pull request overview

This PR updates the project’s CI to fix the failing coverage job (previously using maturin develop without an active venv), adds a dedicated Ubuntu-only pytest matrix across supported Python versions, and modernizes several GitHub Actions used in the workflow while keeping the existing wheel build/test jobs.

Changes:

• Add pytest-cov to the test optional dependency group.
• Introduce a new Ubuntu-only pytest job matrix for Python 3.10–3.14 and a dedicated Ubuntu coverage job (Python 3.12) that installs via pip install -e .[test] and uploads coverage artifacts.
• Update multiple GitHub Actions to newer major versions across existing jobs (checkout/setup-python/artifact actions/attestation, etc.).
