Skyborn 0.3.22

Improvements

• Tropical cyclone potential intensity diagnostics modernization: aligned the workflow with recent upstream validation data and decomposition conventions while keeping the compiled backend as the primary execution path.
• spharm internal optimization: improved the internal spherical-harmonic helper flow so repeated potential-field reconstruction can reuse intermediate spectral results more efficiently.
• windspharm performance improvements: reduced Python-side overhead in the tested wind-decomposition workflow family while preserving established public numerical conventions.
• Growth-rate and pressure-interpolation additions: added compiled atmospheric-column growth diagnostics and pressure-coordinate interpolation support for Chemke-style workflows, including batch evaluation, spectral smoothing, and zonal-wavenumber mode support.

Bug Fixes

• Tropical cyclone potential intensity parity and robustness: fixed remaining pressure, outflow, and missing-column handling issues and improved agreement with the current upstream reference implementation.
• spharm and windspharm regression coverage: added focused tests for updated internal spectral-helper and wind-analysis paths, including shape-validation coverage for the optimized flow.
