v2.7 Update Notes:

Click Issue Fixed: Resolved a bug where the download button on IG Stories was unclickable due to Instagram's transparent navigation overlay.

UI Layout Optimized: Repositioned the download button to the bottom right corner to prevent interference with native mute buttons and the reply bar.

Enhanced Stability: Upgraded the underlying injection logic and added dynamic URL observers to ensure the button displays reliably when seamlessly switching between stories.
