Fixed

• HW-render cores (GLES3) now display frames via thin libretro wrapper — rendersToOpenGL now returns YES for hardware-render cores; the FBO color texture is bound to the shared IOSurface from the Metal view's render delegate; and RETRO_HW_FRAME_BUFFER_VALID frames now trigger didRenderFrameOnAlternateThread so the Metal blit fires each frame. Fixes blank display for mupen64plus paraLLEl-RDP, flycast, Beetle PSX HW (GLES), and similar cores
