Preserve the failed test status in the coverage target.
At Makefile#L325, successful $(FAILPOINT_DISABLE) makes the || branch succeed. The recipe then runs gocov, so the target can succeed after $(TEST_RUNNER) fails. Capture the runner status before cleanup and return it after coverage processing.

In `@tests/config.go`:
- Line 114: Update the newClusterConfig failure path to preserve and combine the
cc.cleanup error with the original newServerConfig allocation error instead of
discarding it via `_ = cc.cleanup()`. Ensure cleanup failures from os.RemoveAll
are returned while retaining the allocation error, and satisfy the repository’s
errcheck requirement.
