graphical.target was gated on network-online.target: cups-browsed orders
itself After=network-online.target and sits in multi-user.target, so the
session waited for NetworkManager-wait-online (DHCP/Wi-Fi association)
before coming up. On the bench VM that was ~140ms, but it's the classic
multi-second boot stall on real Wi-Fi.
Mask NetworkManager-wait-online.service so network-online.target is
reached immediately and nothing in the boot waits for connectivity;
NetworkManager still comes up and cups-browsed browses once the link is
live. Mirrors the existing systemd-networkd-wait-online mask. Enabled at
install (enable-services.sh) and masked on existing installs via
migration.
Verified on a fresh boot: the graphical.target critical chain no longer
passes through network-online.target / NetworkManager-wait-online.
