"""Unit guards for packaged-install detection and its update presentation.

Ticket #27 decides the update-checker behaviour for packaged installs:
background checks stay available as a signal, but every user-visible
update affordance presents the package-manager path instead of release
downloads. The xbps template installs the marker this module reads.
