Stephen Hellings ae528b5132 fix: Electron offscreen rendering and DRM render node propagation 
Three root causes prevented Electron frames from reaching the compositor:

1. --disable-gpu killed Chromium's rendering pipeline, preventing the
   'paint' event from firing in offscreen mode. Replaced with
   --use-gl=swiftshader so Chromium can composite internally while the
   native wo_dmabuf module handles GPU buffer allocation separately.

2. DISPLAY=:0 with no X server caused Electron to fail silently on
   pure Wayland sessions (Ly/logind). Replaced with
   --ozone-platform=headless which lets Chromium's OSR pipeline work
   without any display server connection.

3. WO_DRM_RENDER_NODE was never set, so the native wo_dmabuf.node
   module always defaulted to /dev/dri/renderD128 regardless of which
   GPU the compositor actually opened. Now resolved via sysfs
   (card1 -> renderD128, card2 -> renderD129, etc.) and passed through
   to Electron.

Also: retry EACCES/EPERM as transient during DRM device open (logind
session activation can lag behind libseat's is_active() flag on Ly).
