Qt QML Profiler Skill

Profile a QML application and analyze performance bottlenecks.

Scope

This skill targets 2D QML / Qt Quick applications. Qt Quick 3D (quick3d qmlprofiler feature — Quick3DRenderFrame, Quick3DSync, Quick3DCullInstances, etc.) is not supported: those events are not extracted from the trace, not summarized in the report, and the anti-pattern reference in qml-performance-anti-patterns.md does not cover 3D-specific optimizations (mesh batching, material costs, shader variants, render passes).
