The C24 first cut (#155): a stable, versioned, canonical serialization of a param-generic Composite blueprint plus the data -> blueprint -> FlatGraph loader, closing the graph-as-data loop. Format references nodes by compiled-in type identity over a closed vocabulary (no logic, non-Turing); the loader is generic over an injected resolver with the concrete aura-std vocabulary match living outside the engine (engine stays domain-free). Acceptance: a serialized blueprint runs bit-identical (C1) to its Rust-built twin. Signed under /boss on the Step-5 grounding-check PASS (all load-bearing assumptions ratified by currently-green tests). refs #155
