Print tracked files & env vars

### Description

It would be extremely useful to be able to identify what files/folders are being tracked as inputs/outputs, and what environment variables are tracked for inputs.
This would allow users to be able to determine whether or not they need to include or exclude certain things.

### Suggested solution

Print tracked files/directories & environment variables when running with `--verbose`.
