path to the latest shallalist file downloaded using get_shalla_data
data.frame with the original list, the content category of the domain, and the vintage of the list that supplied it
Shallalist stopped publishing in 2022, so these labels describe the domain as it was
then or earlier, not as it is now. The returned source_last_published column
carries that vintage, and a warning is issued once per session. See
source_vintage.
