✅ Trusted Types compatibility (Edge fix)
Replaced innerHTML usage with secure SVG creation via createElementNS. This prevents TrustedHTML-related errors in Microsoft Edge and other browsers with strict content policies.
🌐 Broader YouTube matching
Updated @match from a specific playlist?list=WL* to a more general https://www.youtube.com/*, allowing for future-proof flexibility (without limiting it to one playlist type).
🧱 Improved injection of delete button
Buttons are now added using safer DOM methods. This improves compatibility and stability across browsers.
🧹 Cleanup of outdated logic
Removed unused SVG string and old insertion logic to make the script more robust and maintainable.
