fix(tests): report skipped integration tests instead of passing them

Every integration test is tagged :slow, so the default run selected none of them and then printed "All integration tests passed" over four "Ran 0 tests" lines.

The target now sums the tests actually run. Zero means it says skipped and names make test-all; a real run reports its count. A failing file still exits non-zero.

This is the third false-green in this Makefile. The other two read $? after a pipeline (7e03862).
