fix: Oracle round 7 — all kwin_wayland_wrapper references → redbear-compositor

Replaced in:
- config/wayland.toml (session launcher)
- redbear-kde-session (KDE session launcher)
- redbear-greeter-compositor (compositor selection)
- test-kde-session.sh (validation script)
- build-system/003-config.patch (durable reapply patch)
- GREETER-LOGIN-IMPLEMENTATION-PLAN.md
- DBUS-INTEGRATION-PLAN.md

Zero kwin_wayland_wrapper references remaining. Redbear-compositor
is the single Wayland compositor throughout the entire repo.
