chore: bump workspace to v2.2.0, sona to v0.2.0

Version bump for new features from #364:
- ruvector-graph: delete_edges_batch, has_edge, get_edges_for_nodes, FloatArray
- ruvector-core: zero-copy insert_batch (impl AsRef)
- ruvector-gnn: ndarray 0.17.2
- ruvector-sona: MicroLoRA set_weights + coordinator persistence
