Construct the spatial autocorrelation analysis module descriptor
Source:R/module_spatial_autocorrelation_registry.R
spatial_autocorrelation_module_spec.RdThe descriptor owns the complete spatial-autocorrelation registry contract: a distance-class correlogram (Smouse and Peakall 1999) with a permutation-based null envelope and per-class p-value, complementing the single overall Mantel r the `ibd` module already computes.
