milestone: desktop path Phases 1-5

Phase 1 (Runtime Substrate): 4 check binaries, --probe, POSIX tests Phase 2 (Wayland Compositor): bounded scaffold, zero warnings Phase 3 (KWin Session): preflight checker (KWin stub, gated on Qt6Quick) Phase 4 (KDE Plasma): 18 KF6 enabled, preflight checker Phase 5 (Hardware GPU): DRM/firmware/Mesa preflight checker Build: zero warnings, all scripts syntax-clean. Oracle-verified.
