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.

Simple 3D animation file format?
IQM is a super simple one, doesn't have everything you listed but it's easy to get working
-
are there any resources for loading and doing 3d skeletal animations without using ASSIMP or another similar library?
IQM is a pretty easy format to deal with, the repo has a Blender exporting plugin for it and an example of how to read it. My loader is only about 400 lines, the rest is just understanding how skeletal animation works well enough to make use of the resulting data.

3D Animations in Raylib
Currently it looks like the support for 3D animations is very limited, with only the IQM format supported. With Blender 3.0+ there is no way to export to IQM (the recommended script https://github.com/lsalzman/iqm doesn't seem to be maintained) and I haven't been able to find any quality format converters to IQM.

For your own engine, do you use an existing format or build your own managing meshes, materials etc in your scene?
If you're going to go to the effort of writing a custom file format, you may as well just write your own Blender export script so that you have the data you want right from the start. If you aren't familiar with it, check out the IQM animation format, which is pretty easy to understand. It has examples of how to load the format, as well as the actual export .py scripts that it uses to export from blender.

Lindenmayer Systems
Very cool. I must check this out.
I implemented some L-system features in my 3D Common Lisp system: https://github.com/kaveh808/kons-9

Profound Beliefs
In some small way I am revisiting the idea with https://github.com/kaveh808/kons-9
We'll see what comes of it.

Symbolics Lisp Machines Graphics Demo (1990)
I began my 3D graphics development on a Symbolics workstation at the MIT Media Lab in the mid-80's. This was before the S-Graphics suite was released. [0]
The outstanding feature of the S-Graphics suite was the polygonal modeler which used a winged-edge structure that was far ahead of its time. It survives conceptually in the Wings3D system, which is a quite faithful copy of that modeler.
And of course you got the extensibility that came with the graphics system being built on Lisp.
But Symbolics was never, as far as I saw, a serious or popular contender in 3D production. Not only was the system expensive, but the hardware could not keep up with SGI's graphics abilities. Furthermore, the mass of CG developers at the time came from a C/Unix background, and rendering especially was so speed critical that C (and Fortran) resulted in faster systems.
Almost 40 years later, I have returned to the idea of developing a 3D system in Common Lisp [1]. We shall see where it leads.

A good codebase to study as a beginner

Coding alone vs coding in a team
As a solo developer of my 3D system, my main focus has been to keep the enthusiasm and momentum going and to enjoy the development process, rather than worrying about how the code might not be optimal in various regards.
