feat: UI polish, DnD fix, navigation, and installer improvements (v1.0.10)

- Fix queue DnD on macOS/Windows: delay ref cleanup in onDragEnd so onDropQueue
  reads correct source/destination before dragend clears them
- Active track highlighting in album tracklist (pulsing accent bg + play icon)
- Marquee scrolling for long titles in Fullscreen Player
- Clickable artist/album in Player Bar and Queue now-playing strip
- Tracklist: format column moved after duration, auto width, kHz/filesize removed
- Settings dropdowns: visible border (base bg + overlay0 border)
- Sidebar: fixed responsive width via clamp(), removed drag-to-resize
- Favorites icon: HandMetal → Star in Random Mix page
- Linux app menu category set to Multimedia (AudioVideo)
- Windows MSI: stable upgradeCode for in-place upgrades
- Bundle: category/description fields at correct config level
- About: Claude Code credit, fixed German MIT licence wording
