Adds section 8.2 documenting the Round 8 follow-up commits:
* c20032435d: Mesa EGL back-buffer allocation in redox_image_get_buffers
(was hard stub - back=NULL always)
* 101ce11844: pipe_loader_redux backend for /scheme/drm/card0
(closes the non-EGL gallium consumer gap)
* 5aa5c96506: kf6-kcmutils git conflict markers resolved
(BLOCKER - shell would have tried to execute literal
<<<<<<< and >>>>>>> strings as commands)
* c73e4227 (relibc): cfgetispeed/cfgetospeed/cfsetispeed/cfsetospeed
real impl on Redox (was 0 or EINVAL unconditionally)
* 9bc6ba0b6e: redbear-compositor keyboard modifier state tracking
(shift/ctrl/alt/logo/caps/num/mod5 with apply_modifier_event)
* 1d930cd425: qtbase open_memstream stub removed (relibc provides it)
* f6420ec8c3: relibc submodule pointer bump
* Documentation cleanups in local/AGENTS.md and local/recipes/AGENTS.md
Combined with the Round 7 follow-up and the v5.8/v5.9/v5.10
parallel sweeps, the surface of unimplemented hard stubs in the
Mesa/relibc/compositor stack is now near zero. Remaining deferred
items (Qt6 Wayland null+8 runtime validation, QML gate in
plasma-framework + kirigami, HW validation) require kernel ABI
work or external hardware.
