Markers are now created via the game's high-level entity factory (0x6707c0) which handles spatial registration, render setup, and lifecycle internally. Removed ~300 lines of dead code: manual game object list insertion, A/B mode switching, parity scanning, and model attachment wrappers. Creation works (markers visible). Destruction still crashes — needs correct destructor for entities created via CreateWorldUnit path (not DestroyWorldObjectAndRelease).
