update-version.sh bumps the pinned Patchwork release: it fetches the latest
upstream tag, downloads both tar.gz assets, updates versions.sh, the manifest
and the metainfo, then self-validates with check-versions.sh. A daily cron
workflow commits the bump and opens a PR labeled automerge; the CI workflow
builds the Flatpak in the freedesktop-24.08 container and auto-merges the PR
once the checks pass.
