FMEA → Control Plan connector engine (#84), authoring UI with injection-safe CSV/Excel/PDF export (#85), 100% line+branch coverage gate (#86), and the Control Plan app added to the mypy gate (#95). Closes the FMEA→Control Plan half of the AIAG loop. All W06 issues closed; every coverage bar green line+branch; full suite 815 passing.
