In-memory implementation of the GraphStore behaviour.

Uses GenServer to store graph data in memory. Useful for testing and small-scale applications that don't need persistence.

Usage

# Start a memory store
{:ok, pid} = GraphStore.Memory.start_link([])

# Use in tests
Arcana.ingest(text, graph_store: {:memory, pid: pid})

# Use with named process
{:ok, _} = GraphStore.Memory.start_link(name: :test_graph)
Arcana.ingest(text, graph_store: {:memory, name: :test_graph})
