docs: QEMU desktop boot evidence — virtio-gpu works, login prompt reached

redbear-full (4GB) boots in QEMU with virtio-gpu-pci:
  - virtio-gpu detected: display 0 (1280x800px) ✅
  - framebuffer console: 'RedBear Login:' prompt appears ✅
  - Wayland compositor: fails on /dev/fd/63 (bash process substitution
    not supported on Redox) — documented as blocker in plan
  - D-Bus system bus: session broker registered ✅
  - KDE session assembly helper: started ✅
  - iommu: no AMD-Vi units in QEMU (expected) ✅

CONSOLE-TO-KDE-DESKTOP-PLAN.md v4.1:
  - Updated compositor blocker: /dev/fd missing on Redox
  - Added QEMU boot evidence date and details
  - Removed P2-rebrand from kernel recipe (line-number conflict
    with consolidated patch — needs rebase)

Remaining errors (pre-existing):
  - fbcond: 'No display present yet' (timing, self-recovers)
  - procmgr: SIGCHLD to PID 1 not permitted
  - cpufreqd: MSR write fails (QEMU, expected)
  - keymapd: Bad file number on scheme read
