Advance redbear-full Wayland, greeter, and Qt integration

Consolidate the active desktop path around redbear-full while landing the greeter/session stack and the runtime fixes needed to keep Wayland and KWin bring-up moving forward.

 This is the single authoritative plan for the Red Bear OS path from console boot to a
 hardware-accelerated KDE Plasma desktop running on Wayland.

 Those documents remain useful for subsystem detail, porting history, and design rationale.
 The earlier reassessment bridge is now retired, and its reconciliation role is covered here together
 with `local/docs/DESKTOP-STACK-CURRENT-STATUS.md` and `docs/07-RED-BEAR-OS-IMPLEMENTATION-PLAN.md`.
