Struct TopologyGroup 

pub struct TopologyGroup { /* private fields */ }

D152 graph-owned release group over ordinary graph-registered nodes.

The group is a label/release handle, not a registry: the graph registry remains the source of truth for describe/find/profile/checkpoint and id retirement.
