S4: extinde suita cu gameplay bomberman + overworld + audio (24/24)

3 teste noi commitate (mutate din scratch in suita):
- audio S1: beep._ctx 'running' dupa Incepe aventura (era NO_CTX)
- overworld: mers cu tastatura (ArrowRight) + iesire blocata pana la final
- arcade bomberman: bomba sparge cutie, BFS AI se apropie, respawn pastreaza progres

Arbore AGENTS.md/CLAUDE.md/tests actualizat 21→24 (14 @regresie + 10 @campanie).
Iteratia 2 COMPLETA (S1+S2+S3+S4). Board: TODOS.md S4 [x].
