Editing tools for an existing FeatureLayer feature (workplans/MESH_DIALOG_TABS_AND_FEATURE_LAYERS_PLAN_2026-09-07.md §3.3): add a hole, add a part, edit vertices, move a whole feature.

Vertex editing follows OpenSWMMVisMapToolEditVertex's contract (maptooleditvertex.h:29-39) — drag a handle to move it, right-click a segment to insert, right-click a handle to delete, Escape to cancel — but generalised: a FeatureLayer geometry has parts and interior rings, so a handle is addressed by (part, ring, vertex) rather than by a bare index. Handles are painted on the overlay, not added as scene items, exactly as the SWMM vertex editor does.

Every committed change goes through EditFeatureGeometryCommand. A drag emits one mergeable command per motion so the whole drag collapses into a single undo step (the MoveNodeCommand::mergeWith idiom); discrete edits (insert, delete, add hole, add part) are pushed non-mergeable so they stand alone.
