Implementation Complete ✅

I've implemented the test peers command. Here's a summary of what was done:

Changes

crates/cli/src/commands/test/peers.rs — Complete implementation:

• TestPeersArgs struct with all CLI flags matching Go reference:
  • --enrs — comma-separated peer ENR addresses
  • --load-test-duration — load test duration (default: 5s)
  • --p2p-relays — relay URLs/multiaddrs (default: the 3 Obol relays)
  • --p2p-tcp-address — listening TCP addresses for libp2p
  • --p2p-disable-reuseport — disable TCP port reuse
• 5 peer test cases: Ping (1), PingMeasure (2), PingLoad (3), DirectConn (4), Libp2pTCPPortOpen (5)
• parse_peers() — parses ENR strings into Peer objects
• parse_relays() — parses relay URLs/multiaddrs
• run() — orchestrates tests, writes output, handles quiet/JSON-file modes
• 20+ unit tests covering filtering, parsing, scoring, and async run scenarios

crates/cli/src/commands/test/mod.rs — Updated list_test_cases() for TestCategory::Peers to delegate to supported_peer_test_cases().

Notes

• Test cases requiring a live libp2p swarm (Ping, PingMeasure, PingLoad, Libp2pTCPPortOpen) return Skip until swarm integration is available
• DirectConn attempts a real TCP connection using the peer's multiaddr IP/port
