vim.pack.add installs on first launch and that needs to reach github, which is
not a given on a work-issued machine behind a proxy. A hard require there takes
down everything below it -- MinuetStatus, the colorscheme, the lot -- and
reports an error pointing at minuet rather than at the network.
MinuetStatus is now registered unconditionally and reports whether the plugin
loaded at all. A status command that only exists once everything already works
is not a status command.
