Keep WaveStar fault parity gate in Python CI

[cmccomb]

What changed

• Preserve the exact generated HDF5 and compact published WaveStar fault source histories from the successful R2025b 141.2 s baseline.
• Run the existing independent Python fault trajectory gate in ordinary CI. The solver receives only pinned sea phases and the exogenous sensor noise/dropout record; MATLAB motion and forces remain expected outputs.
• Retain the live-artifact path and all original numerical limits. This is an already counted case, so parity badges do not change.

Verification

• Portable and live-artifact focused modes: 1 passed each, about 43 s locally.
• Full local suite: 253 passed, 333 skipped in 284.89 s; combined line and branch coverage remains 75%.
• Coverage badge and git whitespace checks passed.
