New Features #

• Custom Overlay Message: Added overlayMessage parameter to multisessionUssd() to customize the overlay text during USSD operations.

Improvements #

• Robust Input Validation: Now validates dialog presence (EditText + Buttons + TextView) before attempting input.
• Text Verification: Confirms text was successfully inserted before clicking confirm button.
• Progressive Retry: Retry delays now increase progressively (250ms to 1000ms) for better reliability.

New Features #

• Invisible Overlay: Added UssdOverlayService to hide system USSD dialogs during multi-session operations.
• Overlay Permissions: Added isOverlayPermissionGranted() and openOverlaySettings() to manage overlay permissions.

• Foreground Service: Overlay service now runs as a foreground service with notification to prevent system kills on Android 8+.

Improvements #
