fix(test): Count parameterized Swift Testing results once

Swift Testing result lines can include parameterized case metadata such
as "with 4 test cases", but Xcode's discovery and run summaries count
that output as one reported test item. Count each result line once so
CLI progress and final summaries stay aligned with discovered tests.

Fixes GH-384
