/**
 * E2E tests for sub-graph lifecycle:
 *
 * 1. Create sub-graphs within a context graph
 * 2. List sub-graphs via agent API
 * 3. Publish data targeting a specific sub-graph
 * 4. Query data scoped to a sub-graph (isolation)
 * 5. Publish to different sub-graphs — verify data isolation
 * 6. Publish from shared memory to a sub-graph
 * 7. Remove a sub-graph
 * 8. Two-node replication: sub-graph publish replicates to peer
