* End-to-End Protocol Test for HiveRelay

* Tests the full protocol lifecycle against live relay nodes:
* 1. DHT discovery of relay nodes via the hiverelay-discovery-v1 topic
* 2. Protomux channel negotiation for seed protocol
* 3. Seed request/response cycle
* 4. Circuit relay channel negotiation and reservation
* 5. Timing for every step
