docs: final stale reference cleanup — all dead doc links removed

Fixed remaining Oracle-found issues:
- docs/AGENTS.md: RELIBC-COMPLETENESS → CONSOLE-TO-KDE,
  RELIBC-IMPLEMENTATION → KERNEL-IPC-CREDENTIAL
- docs/07: QT6-PORT-STATUS + DESKTOP-STACK → CONSOLE-TO-KDE
- CONSOLE-TO-KDE: KWin status updated (no longer has wrapper
  scripts; redbear-compositor provides kwin_wayland separately)

All 13 deleted docs now have zero references in canonical docs.

 The older architecture/roadmap docs under `docs/01`–`docs/05` remain useful, but they should be
 read together with status notes and the newer local subsystem docs.
