FEATURE_LAYER_TO_SWMM_IMPORT — controller between the import dialog (view) and the model side (GISVectorLayer source, SWMMModelLayer target). Splits the work into three phases so the dialog can run the dry run off the GUI thread (MeshGenerationDialog idiom):

1. sourceSpec() / captureModelSnapshot() — MAIN thread; reads the layers/engine into plain data.
2. readSourceFeatures() [static] + buildImportPlan() [pure, see importplanning.h] — WORKER-safe; opens its own GDAL dataset so the canvas's OGR handle (and its spatial filter) is untouched.
3. execute() — MAIN thread; pushes one undo macro of existing Add*Commands + SetAdapterPropertiesCommand / geometry commands.

No widget dependencies — unit-testable headless.
