Added
- In-app update checks (issue #567). Settings > System Status shows the
running version's release date, a channel picker (stable or edge), a
daily auto-check toggle, a Check for updates button, and a changelog
link. A dismissible banner appears under the top bar when a newer
release is available on the selected channel. The daily check can also
send the new Update Available webhook and email notification, once per
version. Backed by GET /api/v1/system/updates (GitHub Releases,
cached 6 hours) and GET/PUT /api/v1/settings/update-check. - The latest and cpu Docker tags now move automatically when a release
is published (release-tags workflow). The stable and stable-cpu tags
still move only when a soaked release is promoted.
