feat: replace ServerQuery with full TS3 client protocol — bot is now VISIBLE

Switch from TCP ServerQuery (port 10011, invisible) to real TS3 client
protocol via @honeybbq/teamspeak-client (UDP 9987, ECDH handshake,
AES-EAX encryption). Bot now appears as a regular client visible to
all users in TeamSpeak.
