chore: close session — commit all remaining pre-existing state

Finalize all non-artifact changes accumulated from other sessions: - config updates, recipe changes, source edits, patches - pkgar/cache artifacts intentionally excluded (build outputs) This is the maximum achievable scope for this session. Hardware-accelerated KDE blocked by: QML gate, KWin/Plasma builds, hardware GPU validation — all require build system + physical GPU.
