Test: e2e Wiring-Lock fuer Deferred-Pass-Rename (treatFilesAsStable)

Ergaenzt den Mechanism-Test um einen End-to-End-Test, der den echten
Produktionspfad runDeferredPostExtraction -> Rename -> Collect faehrt. Sperrt
die Verdrahtung: wuerde jemand das `true` an der Rename-Call-Site (12130)
entfernen, faellt dieser Test (frische Datei landet wieder unbenannt) — der
reine Mechanism-Test wuerde das nicht bemerken. Negativ-Gate verifiziert
(ohne `true` -> FAIL). 624 Tests gruen.
