Mount GAME_STORAGE_DIR/steam-cache → /home/retro/.cache so DXVK/Mesa
Vulkan shader compilations survive container restarts. Without this the
cache lived in the ephemeral session home and was wiped on every Wolf
restart, forcing a full recompile each session.
Also create steam-cache/ in initial setup and update-storage so the
directory exists with correct uid-1000 ownership before the container
first starts.
