[PATCH 0/8] ci: some housekeeping and modernizations

Hi,

this patch series is a result from the discussions in [1]. It fixes a couple of smaller issues in our CI and bumps jobs that use EOL Docker images to instead use supported ones.

Passing test runs can be found at [2] and [3] for GitLab and GitHub, respectively.

Note that I've also merged the Meson changes (ps/meson-improvements at ce4a600322 (gitlab-ci: fix hanging MSVC jobs, 2026-09-24)) in there so that GitLab passes, but those are not strictly required as a dependency.

Thanks!

Patrick
