Canary for the move of ubuntu-latest to Ubuntu 26.04 (rollout 2026-10-19 to 2026-11-19, actions/runner-images#14748): every ubuntu-latest in the workflows reads ubuntu-26.04 here, so this pull request's checks are the repository's CI on the new image.

Not to be merged. What fails here is fixed on main in its own pull request; this one is closed afterwards. Explicit pins (ubuntu-24.04, ubuntu-24.04-arm) are unchanged, as GitHub leaves them. Jobs that run only on tags or schedules (release builds, wheels) are not exercised by a pull request.
