v1.6.9 - Fix permanently stuck HUD CALIBRATING state

Deployment sequence initiated for version 1.6.9. This transmission contains critical updates to the core engine and agentic capabilities.

Transmission Details

• Fixedgame_loading flag now clears after 10 s even if the ETW FPS tracker returns no data (Vulkan, OpenGL, or elevated-permission failures)
• Changed CALIBRATING condition from 'frame_count<30 OR fps==0' to 'frame_count<30 AND fps==0', preventing infinite stuck state
