Stasis ignores /etc/xdg/ and only reads ~/.config/stasis/stasis.rune
(primary) or /etc/stasis/stasis.rune (fallback). On first start with no
user config it writes its own hardcoded default, so Moonarch's tuned
idle plans were never active on fresh installs.
Seed the template from /etc/xdg/stasis/stasis.rune into the user home
before stasis ever starts, only if the user file is missing. See
DECISIONS.md for verification against upstream v1.1.0.
