Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Looking for good (low level?) Elliptic Curve library
Much of what you'll find highly visibly will be high-level libraries, but look at their dependencies. For example, from the ed25519 library you may find ed25519-dalek, and from there you could find curve25519-dalek which deals in point encodings and that like. (I don't know these particular libraries; they might help or just serve as an example of a viable exploration path).

Identity element in ECC
What lib are you using? I would probably suggest to use the Ristretto Group abstraction for safety. The curve25519-dalek crate has that.
-
How mathematically intense can theoretical cryptography get?
Grabbing an abstraction like the Ristretto Group with implementations available curve25519-dalek, can get you very far. You can build stuff like ECIES, Diffie-Hellman, Schnorr Signatures, Aggregated Signatures, etc, without requiring entering the details of EC math.
