mrambossekandClaude Opus 5 d5e15816b5 server: fix egress-MTU probe — connect the socket before reading IP_MTU ...

IP_MTU getsockopt returns ENOTCONN on an unconnected socket; the v0.3.4
probe set IP_MTU_DISCOVER and Sendto but never Connect'd, so every probe
errored. UDP-connect (no handshake) pins the route so IP_MTU reflects the
path; switched to Write (two return values). Sysctl audit already flagged
the four real fmr issues in v0.3.4; this makes the MTU proof report.
