Hand-model the CRI ADX2 (audio) + CRI Mana (movie) SDK surface exercised by the copied
audio/movie engine files (AudioManager/Voice/Se/Effect/MoviePlayer). No decomp source
exists; signatures mirror the real CRI API as called at the sites (arg counts/types from
the call sites). All no-op, cosmetic, off the battle path. Reconciled with the empty CRI
stubs already in SdkStubs (CriAtomExAcb/CriAtomExPlayback/CriManaMovieMaterial).
