Refines #41's blueprint-definition render. The [param:<name>] marker nodes #41 added bloated the ASCII MACD graph (three extra nodes + fan-in edges); this moves the interface into the title line and folds names into the leaf labels that already exist: - title is the composite's typed signature, e.g. macd(fast:i64, slow:i64, signal:i64) -> (macd, signal, histogram) (param kinds from the aliased leaf's factory params via a new ScalarKind->lowercase kind_str; output NAMES only — output kinds need a pre-build factory interface, deferred to #43) - leaf labels fold aliased param names: [EMA] -> [EMA(fast)] - unnamed interior input slots render as ordered stubs: [Sub] -> [Sub(#A,#B)] (count/order derived render-side from c.edges() + c.input_roles(), no engine schema needed; arity-1 nodes get no stub) - outputs de-prefixed: [out:macd] -> [macd]; the [param:*] marker nodes are gone - two stale doc comments corrected: render_definition's [param:] prose and node.rs LeafFactory::label (the renderer went flat in 0017, so the cited ascii-dag cluster-garble rationale no longer applies — wide labels are safe; the factory label stays bare because alias names are composite-level) Render-only: no engine/ParamAlias/param_space change. compiled_view_golden byte-identical (C23 guard — verified untouched in the diff); aura run --macd deterministic and unchanged (total_pips 0.1637945563898923, 3 sign flips). The title format change repinned five .matches("name:")->.matches("name(") definition-count asserts (sma_cross/outer/inner/dup/macd); the stub separator is "," (no space) to match the [Sub(#A,#B)] surface. Verification (orchestrator-run): cargo build/test/clippy --workspace -D warnings all green; the redesigned MACD render confirmed by eye. refs #41 #43
