This update makes GameUP Overlay clearer and more polished.

Reworked the overlay around one simple promise: GameUP Overlay is read-only and advisory.
Polished the in-game HUD into a clearer GameUP-style dashboard with metrics, advice, and hotkey guidance.

Improved settings snapshot guidance so it is easier to capture the Graphics page and understand the next step.

Cleaned up wording around manual changes, retest, and comparison so the flow feels better.

Kept the overlay safe by design: it does not change settings for you or send gameplay input.

Added focused tests for overlay HUD text, command availability, retest routing, and runtime safety paths.
