Code Review
This pull request successfully implements the cross-validation test for the CarreauYasudaBlood model, comparing the Python and Rust implementations. It also cleans up several TODO comments, improving code hygiene. The implementation of the validation test is clear and correct. I have one suggestion to improve the robustness of the relative difference calculation to prevent potential exceptions in the future.
| for gamma_dot in test_shear_rates: | ||
| mu_python = carreau_yasuda_python(gamma_dot) | ||
| mu_rust = blood.apparent_viscosity(gamma_dot) | ||
| diff_pct = abs(mu_python - mu_rust) / mu_python * 100 |

The relative difference calculation could raise a ZeroDivisionError if mu_python is zero. While this is not the case for the current model, adding an assertion makes the code more robust and self-documenting about the assumption that the reference viscosity must be positive. This prevents an unhandled exception if this validation pattern is reused for other models where the reference value could be zero.
| diff_pct = abs(mu_python - mu_rust) / mu_python * 100 | |
| assert mu_python > 0.0, "Python reference viscosity must be positive for relative error calculation." | |
| diff_pct = abs(mu_python - mu_rust) / mu_python * 100 |

In @.github/workflows/performance-benchmarking.yml:
- Around line 83-91: The workflow currently has the "Run regression detection
benchmarks" and "Run production validation benchmarks" steps commented out which
makes manual dispatches with inputs benchmark_type=regression or
benchmark_type=production silently no-op; add a validation step (e.g., "Validate
benchmark_type") that inspects github.event.inputs.benchmark_type and fails fast
with a clear error when it equals "regression" or "production" (or alternatively
re-enable the corresponding steps) so users get an immediate failing status
instead of a misleading success; reference the step names "Run regression
detection benchmarks" and "Run production validation benchmarks" and the input
variable benchmark_type to locate where to add the guard.

Fixed an oversight in the previous commit where a reference to `comprehensive_cfd_benchmarks` was missed in the build step of the `.github/workflows/performance-benchmarking.yml` file, causing the CI to continue failing.
