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.
