Adds a zizmor audit of this repository's GitHub Actions workflows and Dependabot config, through the reusable owncloud/reusable-workflows/.github/workflows/zizmor.yml. It's part of an org-wide rollout (pilot: owncloud/notes#577, merged). Once the repo PRs have landed, Zizmor / Zizmor becomes a required check through owncloud/admin.

  • Behaviour: any finding, at any severity, fails the check, with an annotation on the offending line. The check runs on every PR, on pushes to the default branch and weekly.
  • Permissions: contents: read only, so it also works on fork PRs.
  • Config: owncloud/* references may stay on @main. Everything else must be SHA-pinned.

Existing findings fixed (separate commits)

  • dependabot-cooldown: every update entry waits 7 days, as github-actions already does.
  • excessive-permissions: lint-pr-title declares least-privilege permissions (contents: read, pull-requests: read).

zizmor 1.31.1 reports no findings on this branch.

Runs zizmor over this repository's workflows and Dependabot config on
every pull request, on pushes to the default branch and weekly, through
owncloud/reusable-workflows' zizmor.yml. Any finding fails the check.

The caller comment claimed only pull request runs cancel superseded
ones. GitHub keeps one pending run per group, so for other events a
queued run is still replaced by a newer one; the per-event grouping
only keeps a push from cancelling or displacing the weekly run.
