Gate published monopile hydro in portable Python CI

[cmccomb]

Summary

• Bundle the exact pinned monopile HDF5 and compact MATLAB 400 s output channels, with source hashes and regeneration notes.
• Run the existing full-duration wave, excitation, both-body motion/force, and fixed-joint reaction limits in ordinary Python CI.
• Update the measured combined line-and-branch coverage badge from 77% to 78%. This case was already counted; parity badge totals stay unchanged.

Evidence

• Source: successful pinned R2025b run 37858193863, artifact matlab-MONOPILE_HYDRO-baseline.
• Maximum local differences: wave 2.10e-13 m; excitation/total hydro force 5.83e-7 N or N m; joint reaction 2.60e-7 N or N m; body position and velocity 0. Existing gates are 1e-10 m, 1e-5 N or N m, and 1e-8 for motion.
• Full local suite: 258 passed, 333 skipped; 78% combined coverage. Monopile module: 28% to 85%.
• render_coverage_badge.py --check, render_parity_badge.py --check, compileall, and git diff --check pass.
