The lock listener ignores inhibitors but had no playback condition, so it locked the screen at its timeout even during active media playback (screen-off already skipped via playerctl). Add the same playerctl condition to the lock listener.
niri already owns the org.freedesktop.ScreenSaver interface and feeds its inhibitors into the compositor idle notifier, so hypridle's own registration always fails with 'Another service is already providing...'. Set ignore_dbus_inhibit = true so hypridle no longer tries to claim it; D-Bus inhibits are still handled by niri.
Replace the static hypridle.conf with services.hypridle.settings and add required timeout options so each host tunes its own values:
- idols-ai (PC): 15 min keyboard, 20 min screen-off, 30 min lock.
- 12kingdoms-shoukei (laptop): 3 / 6 / 20 min (previous values).
The options have no defaults because the right values depend on the machine. Update the home-manager eval test to inspect the settings option instead of the old config file text.
