Improvements vibe-coded on top of Tony Chan's extension.

new features:
- share button which generates qr code to scan and/or paste url (for PictureInPicture or cast feature from other apps)
- live badge for stream media + limited controls (forward, backward, loop excluded)
- loop current media button
- volume slider with mouse scroll support
- improved thumbnail fetch for Spotify, Twitch and SoundCloud
- slight UI redesign
- Spotify support (a bit buggy)
- options page: hide thumbnails, set media duration for live media
- keyboard shortcut to open extension and mute all media
