- slider DisplayType enums sink to node/sliderdisplaytype.h (canonical engine home); FloatSlider/RationalSlider alias them for compatibility - DropWithoutSequenceBehavior enum sinks to common/dropworkflowbehavior.h - Config errors now go through a registered ErrorHandler hook instead of QMessageBox with a MainWindow parent; the style default no longer depends on the UI style manager - MainWindowLayoutInfo moves to node/project/serializer/ and its panel dependency is reduced to a plain std::map alias (PanelLayoutInfo), breaking the engine -> PanelWidget -> KDDockWidgets chain - ProjectImportErrorDialog moves from task/ to dialog/projectimport/ - remove confirmed-redundant UI includes and give project.h/import.h/ project.cpp the direct includes they were borrowing transitively - project.h includes folder/sequence headers directly (it used both types in its own API all along)
