- Hold AssemblyListManager on AssemblyTreeModel and mirror its
AssemblyLists collection so the toolbar combo can bind to it.
- New ActiveListName ([ObservableProperty]); OnActiveListNameChanged
loads the named list via the manager and rebuilds Root.
- The "seed initial assemblies if empty" fallback now only triggers
for the (Default) list, so switching to an empty user list doesn't
auto-populate it.
- MainToolBar AssemblyListComboBox bound to AssemblyLists /
ActiveListName (TwoWay).
