lib/test/run.ww: fork+wait4 runner; each @test runs in its own child,
abort/SEGV/FPE decoded from wait-status, failures recorded and the run
continues; exit = fail count. Tests are hermetic: module globals do not
persist test-to-test (fresh fork image; sanctioned divergence from
harec's shared-process __test_main, no setjmp/signal layer needed).
-T synth (both stages) emits a module-global (str,*fn() void) table +
return run(table) instead of straight-line calls. Driver twins bundle
lib/test under test mode and gain ww test -c/-o (go test -c) so the
byte-id gates diff the same artifact the real path builds. Gates
989/910/997 rewired onto it; new 911 pins record-and-continue across
all three fault classes; 949 +3 rows. (#17-team commit-2)
