Graph Interface

Phase A adds graph/topology exports to support future GNN-based work without changing the default flat RL state.

`get_topology_metadata()`

Returns:

feeder_id
scenario_id
node_count
edge_count
active_edges

`get_graph_data()`

Returns plain Python/NumPy structures:

adjacency
edge_index
node_ids
active_line_data

Design Rule

These graph exports are additive. The default RL state vector remains unchanged in Phase A.
