Resolves the #181 design pass (option c: ledger declaration, no lockstep mechanism). The aura-new templates (scaffold.rs) are the canonical authoring shape and evolve with the engine; the cycle-0102 demo-project fixture is an intentionally frozen known-good twin for the load-boundary tests. Deliberately NOT lockstep-guarded: no consumer requires the copies to match (skeptic-verified — nothing treats the fixture as what aura new emits), each is e2e-guarded on its fitness for purpose (build/load/ charter/deterministic run; blueprint wiring is pinned in neither, stated honestly after an adversarial skeptic pass refuted the stronger claim), and an equality guard would convert deliberate template improvements into forced churn of the frozen fixture — the same cross-purpose coupling that rules out regenerating the fixture from the scaffolder. closes #181, refs #180
