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.

Coordination chemistry simulations
Have you tried using GFN2-xTB (https://github.com/grimme-lab/xtb)? It is essentially the fastest method you could use, after forcefields, but is designed as general-purpose tool. I haven't tested it with Zn, but it's worth a try.

CompChem Project Ideas for an Undergrad?
I would recommend getting xtb (https://github.com/grimme-lab/xtb) and exploring some possibilities. The calculations are lightning-fast, so you have a quick feedback loop and you can quickly test different ideas. You can look at recent publications to get an idea of what people are doing.

Considering Julia versus Fortran for a project
the xtb and dftb programs are actually excellent example of well-written, clear, modern fortran codes. I've learned more from reading these codes than from any other resources.

EVB(Empirical Valence Bond) in Gromacs?
That being said, reading just the first papers that showed up on google, it looks like Q6 is an opensource software that is based on Gromacs and has a similar input/output regime as Gromacs that is capable of doing EVB. Repo is here: https://github.com/qusers/Q6
What are some alternatives?
