Retired last commit, deleted now at the maintainer's call. Mattermost
ended support in 2023, the community repo is asking for maintainers, and
the image had not been rebuilt in 1042 days — the staleness signal's
worst case after speedtest. Vikunja covers the same ground and is
actively developed.
Self-contained: every reference lived inside containers/focalboard/ plus
its generated manifest entries, so nothing else needed touching. Git
keeps the history.
Anyone with it already installed keeps a running container and their
data — removing the template only stops NEW installs. Their app will now
report as unknown in the App Center rather than offering an update,
which is the honest state for software with no upstream.
