Headless/store commit callbacks for B-layer consumers.

Use this layer for controlled graph synchronization, analytics, and transaction-driven integrations. NodeGraphPatch is the full-fidelity primary payload; node/edge changes are a lossy XyFlow-style projection.

Ordering guarantees (per GraphCommitted store event):

1. on_graph_commit
2. on_node_edge_changes
3. on_nodes_change (if non-empty)
4. on_edges_change (if non-empty)
5. on_connection_change for each derived ConnectionChange
6. on_connect/on_disconnect/on_reconnect for each derived ConnectionChange
7. on_nodes_delete / on_edges_delete / on_delete for derived removals

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
