Subject: [PATCH 1/3] ci: add zizmor workflow audit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

- dependabot-cooldown: composer updates wait 7 days too, as github-actions
  already does.
- excessive-permissions: lint-pr-title only reads the repository and the
  pull request.

Subject: [PATCH 3/3] fix(ci): address review of the zizmor rollout
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Only the zizmor caller's concurrency comment changes: GitHub keeps one queued
run per group, so for non-pull-request events a newer run still replaces a
queued one; the comment now says so instead of claiming only pull request
runs are superseded.
