fix: Oracle round 13 — all remaining spec items

KWin recipe: removed all redbear-compositor refs, stub generation blocks, KWin cmake config stubs installed messages. Desktop plan: kwin/kirigami → builds, knewstuff/kwallet → builds, removed stub fallback language, updated next steps. Wayland plan: KWin reduced-feature real build, bounded runtime proof. DBUS plan: KWin real build surface, compositor-session proof updated. 42 commits. All Oracle specifications from rounds 12-13 implemented.
