Add test verifying gwpopulation_likelihood_model matches standard likelihood

[Copilot]

Add numpyro test for gwpopulation_likelihood_model

• Explore repository structure and understand existing code
• Create test file for numpyro module (numpyro_test.py)
• Write test comparing gwpopulation_likelihood_model with HyperparameterLikelihood
• Ensure test uses same setup as test_likelihood_evaluation in example_test.py
• Run test to verify it passes
• Run code review and security checks
• Fix linting issues (black formatting)

Summary

Successfully added test/numpyro_test.py with a test that verifies the gwpopulation_likelihood_model function produces identical likelihood values to the standard HyperparameterLikelihood.log_likelihood_ratio method.

The test:

• Uses the same model setup as test_likelihood_evaluation in example_test.py
• Tests both with and without selection effects using @pytest.mark.parametrize
• Properly executes the numpyro model using numpyro.handlers.seed
• Sets predictive_resample=False to ensure deterministic comparison
• Verifies likelihoods match to within 1e-6 tolerance
• Passes all pre-commit linting checks (black, isort, flynt)

Original prompt

On numpyro.py, Add a version of the example test using gwpopulation_likelihood_model verifying that the same likelihood is obtained.

@copilot It looks like the new file doesn't follow the required linting methods and is failing the pre-commit tests.

Fixed in commit ecc12d4. The file now passes all pre-commit checks (black, isort, flynt). The only change needed was removing trailing whitespace.
