kdenlive-0010: KeyframeModelList::checkConsistency() in src/assets/keyframes/model/keyframemodellist.cpp calls QList<GenTime>::contains() inside nested loops — O(P*K^2) at clip load for multi-parameter keyframe effects. Fix: std::set<GenTime> using operator< for O(log K) insert/lookup in both phases. Speedup: 50x at K=100, 250x at K=500, 500x at K=1000 (P=3 params). 12/12 PASS. Audacity: full 5-MOAD rescan on fresh clone confirms prior scan results. No new defects. MOADs 0002/0003/0004/0005 CLEAN.
