Transaction Science 3354465adf ci: run joule-code-remediate's formal gate against a real z3
joule-code-remediate's formal gate shells out to z3, and neither job that
tests it installed a solver: joule-code-rs in standards-build, and the
joule-code conformance gate. Its z3 tests used to return early without a
solver, so CI passed without ever running the real-solver path.
sandbox-meter/cpu-rail-liveness (#114) makes those tests assert in both
branches, and adds JOULE_FIX_EXPECT_Z3=1 to turn a missing solver into a
failure.

joule-code-rs now joins the `z3: true` matrix entries, as
joulecontract-rs already does on the same runner kind. The conformance
gate installs z3 the same way. Both set JOULE_FIX_EXPECT_Z3=1 where z3
was installed. Elsewhere the variable is empty, and only joule-code-
remediate reads it.
