Per IFC4+, IfcContext is the abstract supertype of IfcProject and IfcProjectLibrary; library-only files legitimately contain only IfcProjectLibrary as their root context. Bonsai assumed an IfcProject was always present at three crash sites: the parent-library enum (reported in #8183), RefreshLibrary's tree view, and AddProjectLibrary. Introduce tool.Project.get_root_context() that prefers IfcProject and falls back to IfcProjectLibrary, and route the three sites through it. get_parent_library() now returns None for a root IfcProjectLibrary; get_project_hierarchy() and the EditProjectLibrary parent-swap branch handle that. AddProjectLibrary creates the nested sub-library via IfcRelNests when the root is an IfcProjectLibrary, matching the existing convention for library-under-library nesting. For the separate "Open IFC Project" path, abort with a friendly error pointing users to Project Setup -> Project Library -> Select Library File instead of letting set_units() crash deep in the importer. Closes #8183. Partly generated with the assistance of an AI coding tool.
