Skyborn 0.4.0

New Features

• Atmospheric Diagnostics Expansion: Added new compiled diagnostics and Python bindings for atmospheric-column workflows, including DCAPE and the updated tropical-cyclone / growth-rate calculation paths.
• Hybrid and Sigma Interpolation Modernization: Expanded the vinth2p family with clearer column-major and C-order entry points, improved ECMWF handling, and updated hybrid / sigma remapping helpers.

Improvements

• Spharm and Wind Analysis Refactoring: Refined spherical-harmonic and reduced-vector-wind internals to reduce wrapper overhead, improve caching, and make the public flow clearer.
• Plotting Pipeline Acceleration: Moved more scatter and curly-vector validation / sampling work into native helpers to reduce Python-side overhead and temporary-array churn.
• Build and Documentation Cleanup: Continued Meson build modernization and refreshed documentation and tests around the reorganized interfaces.

Cleanup

• Legacy API Removal: Removed the old Iris interface and other unused legacy paths, and tightened the wind-analysis / spectral-helper APIs.
• Regression Coverage: Added focused tests for the updated interpolation, plotting, spectral-helper, and wind-analysis paths.
