PR2: unifica contractul _campaign la final in libJS.campaignDone()

Payload-ul parent.nextRoom({idx,stars,letter}) era scris identic in 3 locuri
(terminal finale(), SNIP.finalJs showFinal(), classic next()). Acum traieste o
singura data in libJS.campaignDone(), langa roomReady/beep/onerror.

Decizie: NU am pus terminalul pe showFinal() din SNIP (cum sugera formularea
initiala) — showFinal randeaza modal #fOverlay, dar terminalul are finale CRT
stilizat (ASCII 'EVADARE REUSITA' + RESTART), on-theme intentionat. Fortarea
modalului ar fi regresie vizuala pe terminalul standalone. Am unificat doar
ramura _campaign (payload identic), prezentarea standalone neatinsa.

- terminal finale(): say([...], 'ok', campaignDone)
- SNIP.finalJs showFinal(): if(_campaign){ campaignDone(); return; }
- arcade/chat/point primesc campaignDone via showFinal automat.
- classic ramane bespoke (nu foloseste libJS) — pliere = D7 (documentat in TODOS).

Suita 25/25 (terminal standalone + camere terminal in campanie E2E). Demo-uri
libJS regenerate; exemplu-clasic.html neatins.
