Creating this as a draft pull request first. I have more cleanup to do and tests to add, but I wanted to throw this out for comment first before digging in there to see if the basic algorithm seems solid. This current code works when I did some basic sniff testing on it.

Ideas that I'm working with:

• To show our kernel selector list we need to search and crack open kernel specs associated with the current resource. The selector needs the full json for stuff like display name and checking associated interpreters
• Caching doesn't really help here the same way it does with finding. Finding can look into the cache, then search more. But we need everything associated here. And even if we have paths in the cache we can't assume that the files are still there and that the file contents are still the same
• For the slow things: finding the files, reading json. We want to do them as little as possible so save our results in maps
• This is slow, but it's prewarmed at startup time.

Only two issues are blocking for me, others are completely optional comments.

• I'd like to see cancelToken not being passed into a private method (explained)
• Might want to remove hardcoding of / in glob search (not sure it will work on windows, either way, better to avoid hardcoding).

Thanks for taking a look Don. Much appreciated.

Kudos, SonarCloud Quality Gate passed!
