graphical-session.target ships RefuseManualStart=yes and BOS has no
session manager to activate it properly (the same issue worked around
for breadclipd) - breadcrumbs doesn't need a Wayland session anyway,
so default.target avoids the problem entirely.
breadcrumbs had a watch subcommand meant to run continuously but no
systemd unit anywhere, so bakery installs never actually started it -
Wi-Fi profile config in bos-settings had no daemon consuming it.
