Fixed #

• Updated README documentation to use correct pub.dev dependency syntax.

Added #

• Overlay Alignment: New OverlayAlignment enum (center, topLeft, etc.) in OverlayConfig for easy positioning.
• Data Passing: showOverlay(data: ...) now accepts initial data to be sent immediately to the overlay.
• Visibility Check: Added isOverlayVisible() to check if the overlay window is currently on screen.
• Reset on Hide: Added hideAndRestartOverlay() to hide the window and reset the engine state (optimized with deferred restart).
• Transparency Fix: Switched to FlutterTextureView to resolve background frame issues, ensuring true transparency.

Changed #

• Breaking: OverlayConfig.gravity (String) replaced with OverlayConfig.alignment (OverlayAlignment enum).
• Breaking: Removed manual initializeOverlay() and entryPoint parameter in showOverlay. The overlay now auto-initializes using @pragma('vm:entry-point') void overlayMain().
• hideOverlay() now preserves the engine state (keeps it running in background). Use hideAndRestartOverlay() for a full reset.
