try/except; remove the try/except around np.testing.assert_allclose so the

Keep the force-balance assertion authoritative.
Catching AssertionError and only printing it makes this test pass even when the contact-force regression is still present. That removes CI coverage for the behavior this test is supposed to protect. If this is still flaky, split the new penetration invariant into its own test and keep the force check as a real failure/skip/expected-failure instead of a silent pass.
