source filtering capacity

[blaggacao]

I want you to suggest having a look at the source filtering capacity that comes with https://github.com/NixOS/nixpkgs/pull/112083 for making it available in makes.

I think it will be of good use especially for the linters & such.

Yes, I think we can create nice file/folder pickers out of it,

The most complex case we've needed so far is picking all files with a given extension in a folder,

It's already embeded in the framework (projectPathsMatching). We are missing docs though, thanks for pointing this out!
