Usage: Scripts/package/bootstrap-native-daemon.sh [--apply] [--no-packagekit]

Detects the host package manager and prints, or with --apply runs, the native
install command for the Burrow daemon package. This is the host-side bootstrap
equivalent the Flatpak GUI can point users at when PackageKit is unavailable.

This assumes the Burrow native repository for the detected package manager is
already configured. Repository setup should be explicit because it establishes
package trust roots.
