+Fixed double-counting of subtest failures in the final test summary. Subtest failures are now reported separately as "subtests failed" instead of being counted as regular "failed" tests, providing clearer statistics. For example, a test with 3 subtests where 1 fails and 2 pass now shows "1 failed, 1 subtests failed, 2 subtests passed" instead of "2 failed, 2 subtests passed".
