bbob-jax v1.3.0

Release v1.3.0: Registry API Update & Global Minima Verification

💥 Breaking Changes

• Registry API Update: The registry and registry_original now return a tuple (func, f_opt) instead of just the function instance.
  • Old: fn = registry["sphere"](<ndim=2, key=key>)
  • New: fn, f_opt = registry["sphere"](<ndim=2, key=key>)
• Plotting Utilities: plot_2d and plot_3d in bbob_jax.plotting updated to accept the function instance directly (unpacked from the registry tuple).

🐛 Bug Fixes

• Sphere Function: Fixed sphere implementation in bbob.py to correctly include the f_opt offset term.
• Global Minima Verification: All functions verified to reach their true global minimum value (f_opt) at the correct input (x_opt).

📚 Documentation

• Interactive Usage Guide: Converted docs/usage.md to a Jupyter Notebook docs/usage.ipynb with updated examples.
• API Updates: Documentation reflects the new (func, f_opt) return signature.

🛠 Maintenance

• Tests: tests/test_example.py updated to verify the new registry structure.
• Verification: Added robust global minima verification script tests/verify_global_minima.py that handles complexity of internally generated optima.
• Scripts: scripts/update_plots.py fixed to align with API changes.
