Slice AU.4 — Tools → Generate Mesh… dialog.

The dialog owns the QWidget side only; all heavy computation is done in a QtConcurrent worker so the UI stays responsive. The pipeline is split into two phases:

1. collectInputs() — main thread, reads widgets + SWMMModelLayer.
2. runMeshPipeline() — worker thread (QtConcurrent::run), no widget access. Cancellation is checked between every major stage via QPromise::isCanceled().

Hole support: every interior ring of a boundary polygon is turned into a set of constraint segments + a centroid seed point that tells Triangle to leave that region unmeshed (OGR interior rings → g.addHole()).
