Final iteration of cycle D: aura sweep persists each point's RunReport to runs/runs.jsonl; aura runs list prints every stored record; aura runs rank <metric> prints them best-first. sweep_report splits into a production sweep_family() + a #[cfg(test)] renderer; process goldens run in a temp cwd so persistence never dirties the repo; /runs/ is git-ignored. refs #33
