Import it from @grafloria/engine.

SelectionManager provides advanced selection operations

Implements 12 selection patterns from industry research:

• Hierarchical: children, descendants, ancestors, siblings, tree
• Graph: connected, connected component, path
• Group: group members, groups containing
• Filter: by type, by filter, in rectangle
• Bulk: select all, invert selection
