feat(core): traceroute and tcpdump after Java, measured against Java

Browse Source 
TerminalRun adds nine stories: traceroute in the LAN, through the router,
unreachable, without a route, to no one, to the host itself, errors and
Ctrl+C; tcpdump on two hosts. traceroute counts failures across hops as
Java does and takes an error that carries its probe; tcpdump tells each
frame's highest capture row with its time of day, at once.

Departures from Java: traceroute tells its summary before the end mark
(Java after it, where its window shows no text) and calls a host at the
20th hop reached. arpsend is not built.
