julian.kiedaischandClaude Opus 5.5 a867c33d64 feat(core): traceroute and tcpdump after Java, measured against Java 
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.

// Runs a story of FILIUS' command line (Terminal) on terminal-net in Java
// FILIUS and records what really happens: every frame each card saw, Java's
// tables of them, and everything each host's command line told its window
// (each text and each Boolean "busy" mark), with the time.
//
// TerminalRun <scenario.json> <story> <milliseconds> <out.json>
//
// terminal-net: the client 192.168.0.20 (gateway .1, DNS server .10), the
// DNS server .10 (no gateway, no DNS server), .30, .31 (the echo server on
// 55555 in netstat, as on the DNS server), the router .1 / 10.0.0.1, and 10.0.0.2 behind it
// (DNS server 192.168.0.53, which is not there). The DNS server knows
// www.filius.de, filius.de (A and MX), mail.filius.de, multi.filius.de (two
// A), fern.filius.de (10.0.0.2), weg.filius.de (.99, no one) and post.filius.de
// (MX only). A line is typed as the window hands it over
// (Terminal.terminalEingabeAuswerten, the
// first word the command, the others its parameters, then three empty ones):
// the program's thread runs it, one after the other; "^C" is the window's
// Ctrl+C (setInterrupt). Each story's lines with their times are in the
// output (acts), for the core's test to type them at the same times.
// pingLan ping .31, arp typed while it runs
// pingRouted ping fern.filius.de (behind the router), arp on both ends, ping the router's far address
// pingNobody ping .99, which no one has, then by name (weg.filius.de)
// pingUnreachable ping 10.0.0.99 (no one behind the router), 172.16.0.1 (no route at the router)
// pingBroadcast ping .255, ping -b .255, arp, ping (-b) 255.255.255.255, also without a route;
// ping -b .255 from behind the router
// pingSelf ping its own address, localhost, 127.0.0.1
// pingErrors usage, unknown names, no route, no DNS server, a first word other than -b
// interrupt ping .31, Ctrl+C after 1.8 s; again, then arp typed at once; again, then an unknown command
// dns host and nslookup on known and unknown names, localhost, usage, a name with MX only
// dnsTimeout host, nslookup and ping by name where the DNS server is not there
// arp arp after a ping and a lookup, -a, -d, unknown options, no address, the broadcast row removed
// netstat netstat on the client connected to the echo server, on the echo server, on the DNS server;
// the connection closed, on both again
// traceLan traceroute .31 (one hop)
// traceRouted traceroute fern.filius.de (two hops), the router's far address
// traceUnreachable traceroute 10.0.0.99 (no one behind the router)
// traceNoRoute traceroute 172.16.0.1 (no route at the router)
// traceNobody traceroute .99 (no one in the LAN)
// traceSelf traceroute its own address, localhost
// traceErrors usage, an unknown name, no DNS server
// traceInterrupt traceroute 10.0.0.99, Ctrl+C after 3.5 s
// tcpdump tcpdump on .31 and on the DNS server while the client pings .31, looks up a name
// and connects to .31's echo server; arp typed on .31 meanwhile; Ctrl+C on both
