Remove false GPU advertising and fix misleading claims

- Remove false "free GPU acceleration" claims from README and app
- Update messaging to accurately reflect CPU-only processing on free tier
- Add honest performance expectations and upgrade path to GPU tier
- Fix device status messages to show "Free CPU Tier" accurately
- Add note about GPU tier upgrade for faster processing
- Replace misleading GPU benefits with honest CPU optimization claims
