feat(core): packet capture per card after Java's Lauscher, measured card by card

The engine keeps Java's packet capture (capture.ts): per network card
every frame it sent (when it leaves on the cable) or received (also one
for another card), once, with time and number; switches log nothing;
frames the packet loss dropped are kept apart; the capture outlives a
stop and a new start, as in Java, until clearCapture. Per port instead
of per MAC, at most 10,000 frames a card.

expectSameCaptures compares each card's capture with Java's list of that
card in the ARP, WLAN, DNS, TCP, NAT, RIP and single-client DHCP runs.
It found that ScenarioNetwork ignored a switch's learning time (Java ran
300 s, the core the scenarios' 5 s); the oracle sets it now, and the TCP
and DHCP runs are recorded again. A core test found that a new start
numbers frames from 1 again and the capture took them as seen.
