%description
Provides an R-native interface to the 'Circuitscape.jl' and 'Omniscape.jl'
'Julia' packages for landscape connectivity modeling using circuit theory.
Users work entirely in R with familiar objects (SpatRaster, file paths)
while 'Julia' handles computation invisibly. Supports all four
'Circuitscape' modes (pairwise, one-to-all, all-to-one, advanced) and
'Omniscape' moving-window analysis. Methods are described in McRae (2006)
<doi:10.1111/j.0014-3820.2006.tb00500.x> and Landau et al. (2021)
<doi:10.21105/joss.02829>.
