wiki: 2026-11-09 evening refresh 2 - forced GLX reaches glcore; windowed GL waits on kernel kick completion

Refresh STATE-CURRENT, the Main Page and the status/frontier pages: with
SDL_VIDEO_X11_FORCE_EGL=0 the windowed GL path selects libnvidia-glcore,
but the minimal glxgears hangs in the glcore kick wait (poll on the
per-slot /dev/nvidia-modeset fd) while the host completes the beef
notifier memory. The X DDX get-word/notifier completion, the DDX 4 GB
sysmem footprint and physical dispatch of the GL draws remain. Published
to open-iov.org.

 ## 6. What is not claimed
 
 * No OpenGL frame from the emulated vGPU has produced real rendered pixels
   yet; every capture so far is black. GZDoom reaching `MAP01` on Mesa
-  llvmpipe is not a rendered frame from the emulated vGPU.
+  llvmpipe is not a rendered frame from the emulated vGPU, and the forced-GLX
+  run selects `libnvidia-glcore` but hangs in the present/kick wait
+  (`glxgears` reproduces it).
 * No frame-rate or latency numbers.
 * The published two-VM GZDoom demo videos used the labelled `virtio-gpu`/
   `virgl` path, not the emulated vGPU.
