make: wire test-run into make test (pre-push reject gate)

Browse Source 
test-run drives runww.ww over the test/wcc/data/*/case.ww behavior and
//ww:error cases, but was not a prerequisite of any aggregate, so the
reject surface was ungated. With runww's arm now dual-stage, gate it.

Added to the pre-push `test` target only -- not test-unit, not the
test-commit content-key tier. runww execve's its children with nil envp,
so a WW_PKGCACHE override cannot reach them; they fall back to the default
out/.pkgcache that $(TESTS) and the byte-id gates also use. A normal
prereq would let make -j overlap test-run with those writers, so test-run
carries an order-only prereq (| $(TESTS) test-lang test-lang-byteid) and
is scheduled strictly after every default-cache writer. No cache
isolation is added: it would be inert under nil envp, and the ordering
prevents the race.

True per-run cache isolation stays blocked on an os envp() forwarder.

# `all` prereq; test-lang/test-lang-byteid use isolated caches, but ordering
# after them is belt-and-suspenders). The recipe's 990-997/pkgcache default-
# cache tests run only after ALL prereqs complete, so no overlap there.
