- Fix key derivation in both sdk/agent.go and internal/vl1/noise.go:
sort public keys before hashing, use shared key for send/recv
- Adjust docker-compose port mappings to 7150-7153 range (within 7000-7200)
- Add GOPROXY env to Dockerfiles for Go module download in restricted networks
- Verified: all 3 clients connect with 2 peers each, zero decrypt errors
