 1. Discord bot sends a `discord_join` command to c2-core with the target guild and channel IDs.
 2. c2-core picks a free token (optionally the one requested via autocomplete), marks it `in_use`, and forwards the token + channel info to the target edge node over MQTT.
 3. The edge node starts a `discord.py` bot with that token and joins the voice channel.

+4. The bot streams live audio continuously from PulseAudio (`drb_sink.monitor` on the edge node). Icecast is for browser listening only.
 5. On `/leave`, c2-core releases the token back to the pool.
