Masking the units is not enough on its own. install.sh and install_systemd.sh
both COPY unit files into ~/.config/systemd/user, which silently overwrites
systemd's /dev/null mask symlinks and re-arms enforcement -- so a mask alone
loses to anyone running the obvious install command by reflex.
The marker file is the second step: while it exists, no path may install units
or enable timers, and clearing it is an explicit --rearm. --status stays usable
while disarmed but says so loudly, because "armed: no" on its own reads like a
bug rather than a deliberate state.
