TeamSpeak echoes a bot's own channel/server messages back to itself.
Without filtering, a chunked reply re-entered the command path: !help's
output exceeds the ~1024-byte per-message cap, so splitTextIntoChunks
splits it, and the second chunk (which starts with "!artist ...") was
parsed as a new !artist command, loading 20 search results and starting
playback.
Drop messages whose invokerID matches the bot's own clientId at the
transport boundary, before they reach any consumer.
