Two tasks, CLI-render-only (graph.rs + main.rs tests): - Task 1: rewrite render_blueprint to the main-graph + where:-definitions model (composite = opaque node; collect_distinct_composites recursive/deduped by name; render_definition with [in:k]/[out] port markers); drop ItemDisplay/producer_id/ consumer_ids and the nested-composite unimplemented!; behavioural tests RED->GREEN (opaque-node, defines-once, nested-no-panic, reuse-defined-once). - Task 2: recapture the blueprint golden from `aura graph` stdout; full-workspace test + clippy gate. render_compilat untouched (its golden stays byte-identical). refs #38
