A ground-up rebuild of the CoreBot music addon on lavalink-client (Lavalink v4 / NodeLink), replacing the legacy erela.js v3 engine.

• Full playback + queue, vote-skip, autoplay, audio filters, lyrics, grab & playlists.
• 24/7 radio (named + custom stations) and optional Spotify resolving.
• Install: it's just the addon. Drop music.js in your CoreBot addons/ folder; the config auto-generates on first run.

Requires CoreBot (free from CoreMart) + a Lavalink v4 node.
