feat: detect_extensions, detect_files, and detect_folders for every module

detect_extensions, detect_files, and detect_folders for every module

Is your feature request related to a problem? Please describe.

I would like to be able to switch each module on and off conditionally. Surely it would make sense to simply abstract this and make it generally available or not?

Probably a duplicate of #4363.

Would #4439 work for your usecase? You can also point STARSHIP_CONFIG to specific configs. Both need something like direnv or mise to switch env vars based on directories.

I think, this issue could be the answer for the discussion in #4363.

If I understand the issue #4439 correctly, then not really. It would require me to set environment variables dynamically in the folders, right?

I would simply like to say, for example: if there is a .git folder, then activate module x (because it's in a dev folder). I don't want to have to create extra .env files or anything like that.
