v0.3.0

What's Changed

• New MLA/BELA support and test updates: added/updated metadata for MLA/BELA, added BELA simulated-data readers, and refreshed MLA tests and pipeline launch scripts.
• Pipeline and data-exchange improvements: moved/added tools for data exchange, added a crossover partial-derivatives converter for BSW, and reorganized/moved files.
• Numerical/performance improvements: improved xover combination/interpolation efficiency, added blockwise Cholesky decomposition for large systems, sped up load_combine, and corrected the inverse-diagonal stochastic estimator.
• Robustness and bug fixes: improved SPICE wrappers for vectorized calls and out-of-coverage data, fixed altitude units, interpolation behavior, track-average correction constraints, backward compatibility issues, and SpObj evaluation.
• Model/parameter updates: added libration-amplitude parameters, corrected tidal-deformation sign for elevation, upgraded observation/constraint weight options, and removed bad-track parameters and related crossovers.
• Configuration cleanup: introduced/merged the XovOpt dataclass replacement work, loaded vecopts defaults from YAML, and normalized n_proc when loading options from dictionaries.
