Auto-settings rule based on "category"

Discussed in https://github.com/gildas-lormeau/SingleFile/discussions/986

I have been using SingleFile extensively to manually save pages for later reference. I do this mainly for archiving purposes and because i have a bad memory. I've since realized that I always want to save every news article I read. So, I've started to define Auto-settings rules with a specific SingleFile profile for each url of news sites i visit, This profile auto saves pages, and that works fine. However, like most people on the web now, i don't go to just one news source, I get most of my news from link aggregators like google news and reddit. I have to manually add each news website's top level domain (TLD) to the Auto-settings rule with my news autosave profile.

Could it be possible to create an option in the Auto-settings that would let you define a profile based on the "category" of the TDL?

I don't even know if there exists such a list that can be referenced, or how one would go about making one other then a manual process. But if such a list does exist, or can be created easily enough, that would be a pretty great feature.

Start with issue #994 and the linked discussion #986 to understand the requested category-based Auto-settings behavior. Determine whether a maintained category or TLD source is available and clarify the expected matching rules and settings UI before identifying implementation entry points. Done should include an agreed category definition and a testable profile-selection behavior.
