kevinveenbirkenbachandClaude Opus 5.5 b055eece05 feat(ci): keep GitHub-hosted runner labels current through the updater
The workflows pin `runs-on: ubuntu-NN.NN`, so no job moves to a new Ubuntu
release behind our back, but nothing raised the pin either. A sixth job of
`🔄 Update versions` closes that: `utils/update/runner.py` reads the image
table of actions/runner-images, takes the newest x64 Ubuntu label whose
image carries no preview or beta badge, and raises every older bare
`runs-on: ubuntu-NN.NN` to it; arch-suffixed labels stay untouched. The job
opens the change as one PR over `.github/workflows`, so its CI run tests
the new image before it reaches main.

This commit carries the updater's first result: every job now runs on
ubuntu-26.04 (49 `runs-on`).

actionlint 1.7.12, the newest release, does not know `ubuntu-26.04` yet
(rhysd/actionlint#682, fix proposed in rhysd/actionlint#743), so
`.github/actionlint.yaml` declares the label until a release knows it.

act maps each `ubuntu-NN.NN` label the workflows use to the local platform
image, derived from `.github/workflows`, instead of a fixed list that did
not know ubuntu-26.04.
