Every app module now reaches liboakengine exclusively through oakengine_* C calls, EngineEventBridge subscriptions and app-side handle headers (cliphandle/keyframehandle/nodevaluehandle/oakvaluehelper). Direct C++ command construction, engine signal connect()s, and engine type usage in MOC-visible signatures are gone: 557 -> 0 undefined olive:: symbols in oak-editor.
