Function compile_flow_graphs 

pub fn compile_flow_graphs(
    graph: &RealityGraph,
    store: &Store,
    intent: &[(String, Value)],
    symbol_comp: &HashMap<String, String>,
) -> Result<Vec<FlowGraph>>

Compile the canonical flow graphs for every entrypoint.

symbol_comp maps symbol id -> component entity id (same mapping the projection compilers use, so displays agree).
