`core/home/config/nomarchy/default/mako/core.ini` defines the Nomarchy
notification UX — urgency rules, app filters (Spotify silenced),
do-not-disturb mode, and button handlers for "Setup Wi-Fi" / "Update
System" / "Learn Keybindings" notifications. The file was deployed via
the bulk `nomarchy/` dir to
`~/.config/nomarchy/default/mako/core.ini`, but mako reads
`~/.config/mako/config` by default and `autostart.conf` launches it
without `--config`. So mako ran with stock defaults and the entire
themed UX was inert.
Added an explicit `xdg.configFile."mako/config".source` line in
core/home/configs.nix pointing at the existing themed file. mako now
picks up the Nomarchy rules out of the box.
Found during Pillar 8 audit of the desktop stack.
