test: BATS coverage for supporting scripts (functional resilience + sr_resolve)
test-functional-resilience.bats pins dream-test-functional.sh set -e resilience: summary emission even under all-fail, sentinel delivery, bounded set +e/-e around test functions (#428). test-sr-resolve.bats pins sr_resolve 8-case matrix including the dream- prefix strip added post-PR-10 (#430).
