The previous logic considered a shard "passed" if its log contained any
[ PASSED ] line, missing the case where some tests pass and some fail
(both [ PASSED ] N tests. and [ FAILED ] M tests, listed below:
appear in the gtest summary). Exit codes from the test binaries were
also ignored.
Now require both: an [ PASSED ] line, no [ FAILED ] line, and a
zero exit code. Track each shard's PID so wait can surface non-zero
exits.
