giles cbdde5fe63 W14: pin crit-2 signal-return kont non-vacuously (test-only) ...

crit-2's failure mode discards every frame outside the signal site —
including the covering test's own assert — which is why the shipped test
"signal returns handler value to call site" passed vacuously pre-fix. A
plain assert pin would inherit that vacuity on regression.

Add suite gate-crit2-signal-return-kont with a side-effect sentinel: test 1
runs the core.md repros ((list "outer" (handler-bind ... (+ 1
(signal-condition 5))) "end") -> ("outer" 43 "end"); raise-continuable ->
143) then set!s a top-level flag; test 2 independently asserts the flag, so
a dropped continuation fails loudly even though test 1 would "pass". Third
test pins the shipped-test expression (51). 267 passed / 0 failed under
OCaml run_tests.

Test-only: no semantics edits, no push.
