state: 36/48 KDE packages build, 12 blocked — honest final state

The literal task 'build ALL KDE packages' cannot be 100% completed
because 12 packages require upstream dependencies not available on Redox:
- kirigami + plasma* (4): QML JIT disabled — no QQuickWindow/QQmlEngine
- kwin real build (1): Qt6::Sensors port needed
- breeze + kf6-kio + kf6-knewstuff + kde-cli-tools (4): source issues
- plasma extras (3): transitive blockers

What WAS completed:
- Cookbook topological sort fix (root cause — all deps now correct order)
- kf6-attica recipe (183 files, 2.4MB pkgar)
- 12 I2C/GPIO/UCSI daemons archived as durable patches
- Source archival system (make sources)
- Config + all docs synced, no contradictions
