Content access and item sets

The console is unavailable in demo mode; its enabled preference or session override controls visibility. An empty DLC name passes; a registered name uses its cached installed state, while unknown names fail. Steam-backed entries accept any listed installed DLC app. Developer item sets require a local player, clamp granted quality to one through four, can apply configured skills and reset known items before adding their own knowledge. Their optional reset branch creates a grave and clears food, death state, effects and skills.
