Fixed

• Fixed test_manipulation_env_determinism asserting bit-reproducible rewards without requesting a determinism guarantee. Newton defaults to wp.DeterministicMode.NOT_GUARANTEED, under which Warp's atomics may accumulate in any order, so the test failed intermittently depending on GPU scheduling. It now passes deterministic_mode="run_to_run", as the Newton cartpole cases already did.
