nx_initlive_probe.nx -- PROBE (cardinal rule 2): does REAL fork + wait4(WNOHANG) child-liveness work on this host?
(a) fork a child that exits code 7 -> parent polls wait4(pid,&st,WNOHANG) -> detects the reaped pid + exit code.
(b) fork a child that sleeps ~400ms -> wait4 WNOHANG returns 0 (ALIVE) while it sleeps -> reap with a blocking wait.
This is the primitive nx_init_live needs (detect death, distinguish alive-vs-dead). expect_exit: 0
