Standalone headless client that drives a running MARTeApp.ex's
DebugService (TCP 8080 commands, UDP 8081 trace) and TCPLogger (TCP
9090) via marte2debugger/controller's NewHeadlessMarteController, for
the upcoming Test/E2E/suite "debug"/"tcplogger" scenario kinds. Scripts
FORCE/TRACE/BREAK for -mode debug, and triggers+waits for a TCPLogger
log event for -mode tcplogger; reports PASS/FAIL as
result_<scenario>.json/status_<scenario>.txt in -out.
