"""Tests Job 1 — préflight replay non destructif.

Vérifie les fonctions pures du préflight (`_detect_dialogs_static`,
`_build_preflight_report`) et la garantie de non-destruction (aucune mutation des
états replay). Le préflight prouve `commande → workflow → actions non vides →
dialogues statiquement détectables` SANS injecter d'action ni poser de lock.
