fix(versions): never show a 'latest release' older than the installed version

A stale 30-minute update-check cache could render a latest tag below the
installed version right after an update (e.g. 'latest v0.9.9' next to
'installed v0.9.10'), which reads backwards. The passive display now discards a
cached value lower than the installed version until a fresh check resolves it.
