A test/wcc/NNN_*.c with no Makefile-wired binary used to write a SKIP
status, count toward "all N tests passed", and leave MAKE_TEST_EXIT=0.
Two live instances: 953_arrlit_slice_run skipped under a green gate for
weeks (committed unwired at bf1037d, wired in the previous commit), and
a 938 hit the same hole mid-gate. The runner now treats a missing binary
as FAIL naming the file and the target to add, touches the .fail marker,
and so flips the summary + exit code. Closed by construction: make test
builds every $(TESTS) target before the runner walks test/wcc/*.c, so
the missing-binary path is reachable only by an unwired file — there is
no legitimate missing-binary SKIP to preserve. Intentional skips keep
their existing visible forms (UNIT-mode non-enumeration; in-test per-row
skip messages), neither of which folds into the pass count.
Count math: the summary N is unchanged (a SKIP already incremented ran);
what changes is honesty — pre-fix "all N passed" could include silent
skips, post-fix every counted test actually executed. A bare sh test/run
without the make-built binaries now fails loud instead of green-skipping
the whole suite.
