Add dual TS3/TS6 protocol support with auto-detection

The @honeybbq/teamspeak-client library already handles TS6 license block
type 8 (Ts5Server) in its handshake, so voice connections work with both
TS3 and TS6 servers. This commit adds the surrounding infrastructure:

- protocol-detect.ts: Auto-detect server type by probing TS3 ServerQuery
  (port 10011) and TS6 HTTP Query (port 10080) in parallel
- http-query.ts: TS6 HTTP Query client replacing the raw-TCP ServerQuery
  that TS6 servers no longer support (ports 10080/10443)
- client.ts: Protocol-aware connection with auto-detection, TS6 HTTP
  Query setup, and forced protocol override option
- manager.ts: Pass through serverProtocol and ts6ApiKey config options
- connection.ts: Mark legacy TS3 ServerQuery as deprecated for TS6
