Render a wired graph as an ASCII DAG via an `aura graph` subcommand so a mis-wiring becomes visible (the concern of #13). Two selectable views: a blueprint view (composites as cluster boxes, pre-inline) and a `--compiled` view (the flat compilat, boundaries dissolved per C23). Settled in brainstorm: render labels come from a non-load-bearing `label()` default method on the core `Node` trait (a C8 refinement aligned with C23, which already reserves render names citing #13), overridden per node to carry params (SMA(2) vs SMA(4)) so a swap reads back differently. Composites gain an authored name; the engine exposes read-only graph-as-data accessors and stays dependency-free (C16) — ascii-dag lives only in aura-cli. `aura run` is left untouched this cycle. Gates: self-review clean; parse gate a no-op (no spec_validation in profile); grounding-check PASS. refs #13
