//
//  MusicPlugin.swift
//  MioIsland Music Plugin
//
//  Principal class for the music-player.bundle plugin (v2.0.0).
//
//  Wires together the data layer (NowPlayingState + sources/*) and the UI
//  layer (ui/*). Loaded at runtime by the host's NativePluginManager via
//  Info.plist -> NSPrincipalClass = "MusicPlugin.MusicPlugin".
//
//  v2.0.0 is a complete rewrite of the v1.0.0 shell. The old files
//  (NowPlayingBridge / MusicPlayerView / MusicHeaderButton) have been
//  replaced by a layered design:
//
//    NowPlayingState  -> orchestrator + sticky source routing
//      +-> sources/MediaRemoteSource     (dlopen private framework)
//      +-> sources/SpotifyAppleScript
//      +-> sources/AppleMusicAppleScript
//      +-> sources/ChromeWebSource       (JS injection into video/audio)
//      +-> support/ChineseAppDetector    (QQ / NetEase / Kugou)
//      +-> support/HostVersionCheck      (host >= 2.1.7 gate)
//
//    ui/ExpandedView     -> main panel (makeView)
//    ui/HeaderSlotView   -> 20x20 header icon + pseudo-spectrum
//    ui/AlbumArtColorExtractor + ui/SeekBar
//    support/Localization (zh/en)
