metrics: RTT/loss histograms + Ed25519 signing + peer exchange via INIT handshake + file logging to stats/<peer>.dat
- etcp_metrics struct: 12-bucket RTT histogram, 11-bucket loss histogram, 10-min snapshots (>=200 pkts)
- Total counters: packets/bytes sent/rcvd, losses (retrans + probe gap detection)
- CSV append to <stats_dir>/<peer_id>.dat every 10 min
- Ed25519 pubkey exchange in INIT handshake (V3), always present
- Signed metrics exchange via ETCP_SECTION_METRICS (0x0A)
- Received metrics saved as from_<peer_id>.dat with signature hex
- on_metrics_rcvd callback in ETCP_BINDINGS
- stats_dir derived from config file path, mkdir'd at instance init
- Simplified versioning: ETCP_INIT_REQ_SIZE / ETCP_INIT_RESP_SIZE via sizeof
