Code Review
This pull request successfully implements validation tests for the cfd-python bindings by exposing cavitation and hemolysis models from Rust to Python. The new bindings are correctly implemented, and the validation script now asserts that the outputs from the Rust and Python models match, which is a great step forward for ensuring correctness. The changes are clean and achieve the goal of the PR. While outside the scope of the changed lines, it's worth noting that the summary output at the end of the cross_validate_rust_python.py script still contains some outdated information and a 'NEXT STEP' section describing the work that has just been completed in this PR. Updating this would improve clarity for future runs of the script.

Remove extraneous f prefix from strings without placeholders.
Static analysis (Ruff F541) flags these f-strings that have no placeholders:
Proposed fix
- print(f" ✓ Rust values match Python calculations within tolerance")
+ print(" ✓ Rust values match Python calculations within tolerance")- print(f" ✓ Rust apparent_viscosity matches Python calculations for all tested shear rates")
+ print(" ✓ Rust apparent_viscosity matches Python calculations for all tested shear rates")- print(f" Located in: crates/cfd-core/src/physics/hemolysis/models.rs")

Remove or remap the disabled dispatch modes.
With these steps commented out, workflow_dispatch runs using benchmark_type=regression or benchmark_type=production execute no benchmark at all: Line 79 skips the comprehensive run for those values, and the job later still looks for artifacts those steps used to generate. Either drop those input options or point them at a valid bench target.

High-level PR Summary
This PR implements Python bindings for cavitation and hemolysis physics models from the Rust
cfd-corelibrary, enabling cross-language validation testing. It adds PyO3 wrappers forRayleighPlesset(bubble dynamics),CavitationRegimeClassifier(Blake threshold calculations), andHemolysisModel(blood damage index), then updates the validation script to run automated assertions comparing Rust outputs against pure Python calculations for all three models. The changes also fix gitignore to exclude virtual environment directories.⏱️ Estimated Review Time: 5-15 minutes
