The package ships Flathub in /usr/share/flatpak/remotes.d, so the module
declares no remote of its own and checks it instead. Eleven Go tools: list,
runtimes, remotes (naming the desktop's duplicate user Flathub), updates,
unused, disk usage, and install, remove, update and remove-unused, the
system installation's acts through sudo -n and the account's without.
uninstall --unused has no dry run, so flatpak_unused works it out from
flatpak's own answers: an application's runtime and SDK, the extension
points of what is used, and pins. Acts run as jobs inside the bundle,
because an install outlasts a call.
