Improved Button Injection Reliability: The Shuffle Play button is now injected only when the Subscriptions page is fully loaded, ensuring it always appears correctly.
Dynamic Page Load Handling: Added a MutationObserver to detect when YouTube dynamically loads content, preventing missing buttons when switching tabs.
Enhanced URL Change Detection: Now listens for YouTube's AJAX-based navigation (pushState and popstate events), ensuring the button persists without requiring a full page refresh.
Optimized Performance: The script now continuously monitors for changes without unnecessary re-injections, making it more efficient.
